I want to run a Python script using "Python launcher", so that I can use a shebang line to specify the Python environment for each individual script.

I installed Python 3.6 from Anaconda.

However, when I type "py" in the Conda prompt or Windows CMD, it says

'py' is not recognized as an internal or external command.

What should I do in order to use the "py" command to launch a Python script?
