In this video, we will learn how to install VSCode, get the Python extension installed, how to change Python interpreters, create virtual environments, format/lint our code, how to use Git within VSCode, how to debug our programs, how unit testing works, and more. VSCode is a very nice free editor for writing Python applications and many developers are now switching over to this editor. python-version files, and the global default.In this Python Programming Tutorial, we will be learning how to set up a Python development environment in VSCode on MacOS. pyenv then works out which version of Python should be run based onĮnvironment variables. Looks for a program named python, it looks inside the shims directoryįirst, and uses the fake version, which in turn passes the command on to Interpreter (plus other tools like pip and 2to3).
