python 3 and python 2 pips not working in windows

[snippsat]

Do yourself a favor and copy Python37.exe to python3.exe and pip.exe to pip3.exe.
And do likewise with Python 2.7 . (Use pip2)

Then in your scripts, at the shebang use:
#!/env python3 for 3.7
#!/env python2 for 2.7

No this is just wrong,there is no Python37.exe in a Windows install only Python.exe.
As i mention you do not mess or rename anything at all,access to other version in Windows is bye using py.
If you not sure about this then don't give advice that can mess up stuff.
