Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java and XML. Salient Features of Online Python code editor and console. Online Python Interpreter can be used to execute basic and advanced Python program code. You can directly write the code in the editor and execute the code at the same time in the Python online IDE. It supports Python. Python online code editor supports all builtins functions of Python. Online Python IDE and interpreter is suitable for data science and machine learning. It supports advanced Python libraries such as Numpy, Pandas, Scipy, Matplotlib. The online Python IDE and compiler is backed and hosted by Trinker.io.

Integrated Development and Learning Environment (IDLE) is the default editor that comes with the Python installer. It’s a simple IDE, but a great tool to get started with Python without being overwhelmed by features you don’t need or understand yet.

What exactly is an IDE? An IDE is a development environment that provides features that help you write code. Features like:

  • Syntax highlighting: Highlight your code using different colors, making it easier to read.
  • Auto-completion: Shows possible options when you type code, similar to how you use a keyboard on most mobile phones.
  • Run Python code: Make it easier to run your code while you write it.
  • Debugger: A debugger makes it easy to find errors in your code.
  • Version Control System (VCS) support: Integrated client(s) to store your code in a VCS like Git.

Batteries included. With Python versions 2.7, 3.5, 3.6, 3.7 and 3.8, and all the goodies you normally find in a Python installation, PythonAnywhere is also preconfigured with loads of useful libraries, like NumPy, SciPy, Mechanize, BeautifulSoup, pycrypto, and many others.

There are many other features. For example, advanced Python IDEs let you run Python code through SSH, on Docker containers, etc.

Searching for the right IDE can be difficult. If you search on Google for “Best Python IDE,” you’ll find dozens of opinions and discussions about whether something is an IDE or an advanced text editor. The IDE of choice also depends on your work. For example, a data scientist might select an IDE with features that make machine learning or data analysis easier. Network or DevOps engineers might prefer a more lightweight IDE.

Technically, you could write all your Python code in Notepad and run it from the CLI. This works, but an IDE can make your life so much easier. As a beginner, it’s good to start with IDLE to learn the Python syntax. Once you understand the basics, it’s best to move on to something more advanced.

In this lesson, I’ll give you an overview of IDEs and IDE features that help to create Python code.

Visual Studio Code

Visual Studio Code is an open-source text editor / IDE, released by Microsoft. You can use Visual Studio Code for Windows, Linux, and Mac OS. Since its release in 2015, it has been a popular choice for many developers. It sits somewhere in between a lightweight IDE and a text editor on steroids.

There are many extensions you can use. This makes it an excellent choice for network or DevOps engineers. I use Visual Studio Code daily, and besides Python development, here are some of the extensions I use:

Let’s take a closer look at how we can use this IDE for Python code. Once you have installed Visual Studio code, we need to install the Python extension:

Click on the “Extensions” button on the left side, select Python, and click on the Install button. That’s all you need to do.

Features

Now let me show you some useful features we can use for Python code.

Code Linting

A linter analyzes your code for syntax and styling errors. If it finds any, it marks or flags the errors. A quick example is indentation. When you type code that has to be indented, Visual Studio Code automatically indents for you. When there are any indent errors, they show up:

When you want to use a variable that you haven’t assigned yet, it shows up:

Code Completion

When you type code, Visual Studio Code autocompletes it for you:

This can reduce the amount you type but also helps with examples and snippets.

Collapse Code

Do you have a large loop somewhere in your code and want to get it out of the way for a second, so your code is easier to read? You can collapse your loops. Just click on the small arrow:

And it will look like this:

Debug

A decent debugger makes your life so much easier. Until now, you might have added some extra print commands in your code to see the output of a variable, list, or dictionary. With a debugger, you can “pause” and jump into your code at any moment and see the state of all variables.

If you want to try this yourself, you can copy and paste the following code in a .py file and open it in Visual Studio Code:

We debug code by adding a breakpoint. You need to click on the line where you want to pause your code:

Click on the “Run” button in the left sidebar, then click on the “Run and Debug” button:

Visual Studio Code asks what you want to debug. Go for the first option (Python File) and hit enter:

Our code now pauses at the breakpoint, which happens to be inside our for loop. On the left side, you can see the state of all variables:

In the top middle of the editor, the “debug bar” appears. You can use this to take action. For example, the first button is for “continue,” which continues execution of your code until it hits the next breakpoint or when the program exits.

When I click on the first button (continue), the code continues until the next iteration of the for loop. On the left side, you can see that variable “device” is now R1 (the next item in the list we iterate):

You can also open the debug console and type some Python code:

The debug console allows you to play with your code at the current state. Very useful to do some quick testing. Debugging your code like this makes it easier to see exactly what is going on within your program at any given moment.

Online IDE

You can also use an online IDE to code from your browser. In the Python installation lesson, I showed an example of trinket.io, which I use to embed code on this website. An online IDE is an excellent way to run Python code without installing anything on your computer. You can also use it on any device you want.

When you search on Google for online Python IDEs, you’ll find plenty. Another online IDE I like is repl.it. Here is a screenshot:

Here are some of the things you can do with repl.it:

  • Create multiple files and folders, just like you would on a local device.
  • Share your code with a link.
  • Work together simultaneously on your code.
  • Install Python packages.
  • Debug your code.

Mobile

How about writing some code on your phone or tablet? You might not use these IDEs for hours of coding, but for some quick on-the-go testing or learning, it can be useful. You can try Pydroid for Android or Pythonista for Apple devices.

Conclusion

You have now learned what an IDE is and why we use them:

  • An IDE is a development environment with features to make coding easier. Features like:
    • Syntax highlighting
    • Auto-completion
    • Run Python code
    • Debugger
    • VSC support
  • Visual Studio Code is a great IDE/text editor for network or DevOps engineers because of its extensions.
  • An online IDE is useful when you often switch devices or don’t want to install anything on your computer.
  • There are also mobile apps with feature-rich IDEs.

I hope you enjoyed this lesson. If you have any questions, please leave a comment.

  • 10 Best Python IDE & Python Code Editors

Launched in 1991 by its creator Guido van Rossum, Python is one of the main programming languages ​​used to automate specific repetitive tasks. The language has evolved enormously with the contribution of many developers/programmers. If you are new to programming, it is recommended to start with Python. Python interpreters are available on several operating systems such as Linux, macOS, and Windows.

Python is a versatile language, which means that it can be used in many applications ranging from Blender (3D modeling software) to web development. You can write Python code using a shell or shell for small projects. However, if you want to work on larger projects, we recommend using a dedicated code editor or an integrated development environment (IDE). Each Python IDE or code editor differs from the other regarding its features, user interface, and so forth. We have mentioned some majorly used ones as recommended by the Python community.

Before moving ahead, let us first see what IDEs and code editors are and the requirements for a good Python coding environment.

What are IDEs and Code Editors?

Whether you are new to this game or you are a veteran player, you need an IDE (Integrated Development Environment) or a code editor to showcase your coding skills and talent. An IDE is a software that consists of common developer tools into a single user-friendly GUI (Graphical User interface). An IDE majorly consists of a source code editor for writing software code, local build automation for creating a local build of the software like compiling computer source code. Lastly, it has a debugger, a program for testing other programs. An IDE can have many more features apart from these & those vary for each IDE.

Code editors are also software; it is like a text editor with some added functionalities. It is not an IDE as an IDE has many developer tools. Depending upon the language one codes on the editor, it highlights special keywords and gives some suggestions. Sublime Text, Atom, Visual Studio Code are some of the popular code editors.

Requirements for a Good Python Coding Environment

We have listed some major and standard features and requirements required by every project in its build phase and after. A project can have more requirements than mentioned below, but these are the basic ones, and IDE must possess.

  • Save and Reload Source Code

An IDE or editor must save your work and reopen everything later, in the same state it was in when you left, thus saving time for development.

  • Execution from Within the Environment

It should have a built-in compiler to execute your code. If you are not executing it in the same software, then probably it is a text editor.

  • Debugging Support

The debugger in most IDEs provides stepping through your code and applying breakpoints for the code's partial execution.

  • Syntax Highlighting

Being able to spot keywords, variables quickly, and symbols in your code make reading and understanding code much easier.

  • Automatic Code Formatting

This is an interesting feature; the code indents itself as the developer uses loops, functions, or any other block code.

10 Best Python IDE & Python Code Editors

To help you choose your Best Python IDE, we have compiled a list of some of the popular Python IDE. Based on functionality, the number of users, and positive feedback from each user's experience, here is the list:

1. Pydev

Platform: GNU/Linux/macOS/Windows/Solaris

Official website: https://www.eclipse.org/; http://pydev.org/

Type: IDE

Eclipse is an integrated development environment (IDE) historically designed for the Java language. Still, thanks to a system of plugins or extensions, it can be used with other programming languages, including C/C++ and PHP. Pydev is a plugin that allows Eclipse to be used as a Python IDE that also supports Jython and IronPython. Pydev uses advanced inference techniques to provide elements such as code completion and code analysis. The IDE also provides the following features: debugger, Django, an interactive console, basic syntax highlighting, code coverage, etc. It is one of the best Ide for python and Best Python Editor too.

Pydev is free, platform-independent, and promotes excellent integrity with the Eclipse universe. Thanks to the efforts of the developers and the evolution of technology, python development has become almost comparable to Java development on Eclipse, making the experience much more impressive and exceptional.

It was first published in 2007, and Jon Skinner developed it. To create this software, Jon Skinner has adopted three principles:

  • Discreet, minimal interface: we must be able to focus on the text and not a myriad of toolbars;
  • The text is not hidden by the windows;
  • Use as much space as possible: full screen, multi-screen, side-by-side file editing should be possible.

Once you have installed Sublime Text as a Python IDE thanks to the different plugins and packages, you get high quality and powerful IDE that allows you to develop very easily in Python. It incorporates most of the features of a basic Python text editor, including customizable syntax highlighting.

Advantage:

  • Fast with very few bugs (big advantage)

Developed by Microsoft for Windows Linux and OS, VS Code is an extensible code editor not to be confused with Visual Studio. Indeed VS Code is small but complete, and the software is open source under MIT license; this is what characterizes the difference between Visual Studio and VS Code. The first version of the VS Code was published on April 29, 2015. VS Code is comparable to Atom in terms of functionality. Indeed, just like Atom, VS Code is built on Electron, which means that these two programs have almost the same advantages and disadvantages.

VS Code is Microsoft's project, with the highest number of contributors on GitHub. This initiative has boosted Microsoft's notoriety and positioned it as one of the major players in community software. You can add a new language to the environment, such as Python, in this case. Simply download and install the corresponding plugin to adapt it to the environment. Vs. Code is enhanced with features such as the integration of a powerful code auto-completion engine (IntelliSense), a debugging console, and a terminal to launch server commands.

VS Code is very well designed overall, and its main advantage is that it offers an extension-based architecture. Because the IDE is lightweight, it can be extended by adding successive components as needed.

Advantage

  • More than 4700 extensions
  • A powerful code management engine
  • On-demand import of keyboard shortcuts from other Python editors such as Sublime Text or Atom

Disadvantage:

  • Difficulty to find the extension that best suits your needs due to the thousands of extensions available

5. Vim

Platform: Linux/macOS/Windows

Official website: https://www.vim.org

Type: Text editor

Vim is a text editor, an editor allowing the manipulation of text files. Its source code was first published in 1991 by Bram Moolenaar, its main developer. Since then, the software has evolved and been improved by its developer and also by the contribution of the developer community. Vim differs from most other python text editors in its modal mode of operation, note that Vim has three basic modes: insert mode, normal or command mode and command line mode.

Vim is free software and is largely customizable by adding extensions or modifying its configuration file, which means that you can very easily adapt it for development in Python. This software includes a multitude of features such as multi-buffers that support simultaneous file editing, automatic indentation adapted to the language, and many others. To download Vim, simply click on this link https://www.vim.org/download.php.

Python Ide Online

Richard Stallman insisted on the fact that the software must be completely free and customizable without any restriction in programming. After a few years, many versions of Emacs have appeared, including GNU Emacs, initiated by Richard Stallman in 1984 and XEmacs launched in 1991. GNU Emacs uses a powerful extension language called Emacs Lisp that supports advanced tasks such as writing, compiling programs, surfing the Internet, reading email, and discussion forums.

This software is available for free download and is available on all platforms. GNU Emacs uses various customization scripts for development in several languages, including Python.

For Python development, you can use the Elpy extension on Emacs to work with Python projects. This software is very feature-rich. Among its many features, we can mention the highlighting of syntax to differentiate document elements such as keywords and comments; Automatic indentation to have consistent formatting in a file, etc.

7. Atom/Atom-IDE

Platform: Linux/macOS/Windows

Official website: https://atom.io/

Type: IDE

Atom includes most of the functionalities of a basic IDE. Among its features are syntax highlighting and auto-completion. Atom's developers are working on the integration of major programming languages such as Rust or Go. Atom is making progress in improving its performance, and developers are extremely attentive to the needs and opinions of the community, striving to make the user experience more rewarding. There are improvements in the waiting time for opening the software and small improvements in the time required for important calculations to reduce latency. Still, more and more progress is to be expected in the coming months. Atom is one of the best text editor for python.

One of the reasons that have contributed to the Atom's success is its fully customizable interface. Everything can be changed, from the interface to the basic functions. On the other hand, this rather advantageous initiative is also one of the problems at the root of the program's latency. But overall, Atom remains a very practical and functional IDE, and we look forward to program updates.

Advantage:

  • Fully customizable interface
  • Well documented
  • Offers almost everything VS Code has to offer

Disadvantage:

  • Excessive RAM consumption
