Git Bash switching version in python

Question

I have installed Python27 already in my C: drive. I have a code written in Python2.7.x and when I type the statement in Git Bash command line-

python --version

it gives me

3.8.1

How do I run the Python2.7.x script named first.py which is in the following directory

C:/Python27/m1/m1/first.py

@ElpieKay I opened git bash and typed in py -2 but the cursor goes to next line without an output — LGEYH

My fault. Kill the terminal and reopen one. Try winpty py -2 and winpty py -3. If it works, add alias py='winpty py' to ~/.bashrc. — ElpieKay

@ElpieKay thanks for that. It does work and take me to python 2.7.18. How do I add alias py='winpty py' to ~/.bashrc — LGEYH

@LGEYH : How about using a text editor? That's what they are made for. — user1934428

You can check what version of python you have installed by

py -0

You can use to execute your script in python 2

winpty py -2 <your_file>

If you python 3

winpty py -3 <your_file>

If you have more than one python 3 installed on your machine (3.8, 3.9) and you want to test you file in python 3.9

winpty py -3.9 <your_file>

You can add alias command for winpty py by adding alias to .bashrc file

alias py='winpty py'

and now instead of typing winpty py use py instead
