Code Runner Vscode Python3

Write and run Python code using our online compiler (interpreter). You can use Python Shell like IDLE, and take inputs from the user in our Python compiler.

In this post we'll look at how to develop in Python using Visual Studio Code. I'll also show you a few extensions that can make your life much easier while working with Python!

Initial setup

To run a python file you can right click in the editor and select Run Python File in Terminal. Bonus: If you want to run your python code with the code runner extension, in your workspace.
Python is an interpreted language, and in order to run Python code and get Python IntelliSense, you must tell VS Code which interpreter to use. From within VS Code, select a Python 3 interpreter by opening the Command Palette ( ⇧⌘P (Windows, Linux Ctrl+Shift+P ) ), start typing the Python: Select Interpreter command to search, then select.
Visual Studio Code is highly extensible and customizable. Take a look at some of the extensions that make Python development in VSCode a better experience. Python by Microsoft.

When you install Python (which I recommend you do via the official installer), remember in which folder it was installed. And on Windows, make sure to tick the 'Add Python to PATH' in the first screen of the official installer.

Download Visual Studio Code and install it like you would any other application.

Open Visual Studio Code and navigate to the Extensions panel on the left hand side. There, look for the Python extension and install it

Once that's installed, you can open any folder using Visual Studio Code and create a file that ends in .py. The Python extension will use appropriate syntax highlighting and also help you code by offering you suggestions and hints.

You can change which version of Python the extension uses by clicking on the bottom left, where in the screenshot it says 'Python 3.7.4 32-bit'. This will let you select a different version from those you have already installed. Note that if you only have one version, you'll only be able to select that.

The Code Runner extension

Another extension, aptly called 'Code Runner', allows you to run your code more easily than normal. It gives VSCode a 'Play' icon at the top right, and when you click it, the selected code will run.

This is great because it allows you to either:

Select a portion of your code and run it, for example if you want to double-check what it does;
De-select all your code and just open a file, and press the 'Play' icon to run the entire file.

Do note that if you select only a portion of the code and run it, this portion cannot depend on variables or functions defined elsewhere in the code.

The indent-rainbow extension

An extension called 'indent-rainbow' will color every indentation level in Python in a slightly different color, so you can very easily tell which parts of your code are at which indentation level.

This is what the extension will do:

The Rainbow Brackets extension

If you like the indent-rainbow extension, you might also like Rainbow Brackets extension, which highlights nested parentheses, square brackets, and curly braces in different colours, making it easier to keep track of nested brackets.

The vscode-icons extension

While this extension is by no means required to run Python code, I use it and like it very much as it allows me to more easily scan my open files and folders by giving them nicer icons.

You can install this in order to change the icons displayed beside files and folders in your currently open project.

Conclusion

Code Runner Vscode Python 3 Download

That's it! As long as your Python version is in your PATH (which happens automatically on Mac and Linux, and you must tick the box in the installer in Windows), the Python extension will straight work out of the box!

If you have persistent issues, Google is your best friend as tens of thousands of people use this extension, and almost all potential problems have already been discussed and solved in other occasions. The development team is also very helpful in their GitHub page.

The GitHub page also contains extensive guides and information on how to get the extension up and running, it case it's necessary!

Hope this has been helpful and your environment is now all set up. Happy coding!

Introduction

Are you tired of reinstalling extensions on each of your computer(s)? How about when you have to reset computer entirely? Or, how about you're an instructor, a hobbyist, or just 'getting your feet wet' in the fine craft of Python programming who does not know which extension(s) to select to get the job done both efficiently and effectively. Regardless, please do not waste time and energy on something so tedious as a process of installing extensions. Extensions are, in a word, awesome! Their premise is to extend the features and functionality of Visual Studio Code.

What extensions will I get by selecting this extension pack?

Glad, that you've asked! Please find the supervening extensions. Of course, I always love to hear your suggestions to improve this extension package. To do so, please create a new issue in the Issues Section. After all, the ultimate goal for this extension pack is convenience at the click of one button.

Recommended Theme for Python Development

Chromodynamics Theme: A VSCode plugin extends Python programming in VSCode through a highly recommended (at least, from yours truly!)dark color scheme from MagicStack. Note: This works well with MagicPython, which is included below. :-)

Recommended Extensions for Python Development

AREPL for Python: A Visual Studio Code extension that automatically analyzes Python code in real-time as you code.
Better Comments: A Visual Studio Code extension whose premise is to categorize your comments (annotations) in your Python code, through:

- Note: Please be advised that you will need a Python distribution. Depending on what you utilize Python programming for, I can recommend without hesitation either the official Python Distribution or Anaconda. Anaconda graphical user interace is best for data science, artificial intelligence, and machine learning. Conversely, the official Python distribution is best for application development (desktop, web, or GIS). I have included the weblinks to the respective homepages, since usually pages are moved and the direct weblink would be dead. :-(
