Switching Between Python Versions in Windows is really simple with PyLauncher. Also you can use a special comment on the top of python scripts to tell PyLuncher whether the python script will run using Python 2 or Python 3. In this video I showed you exactly how you can easily switch Python versions in Windows. If you have both Python 2.x and Python 3.x installed on your Windows computer and want to use both Python versions then this video is right for you. The comment you need to put at the top of the Python scripts is...

-- For Running a Python Script Using Python 2
#!python2

-- For Runnning a Python Script Using Python 3
#!Python3

Some experts recommend to slightly modify Python files and in this way they trick Python to launch their desired Python version. But I strongly recommend you to stay away from this kind of tricks as this can lead to serious problem when you go for deploying Python software. Rather Python latest versions are packed with PyLauncher which can be used to switch between Python 2 and 3. Form command line you can use py.exe to run Python 2 and 3 side by side.
