There are a couple of ways you can tell a script to run with a specific version of Python, commonly you'd use a shebang:

#!/user/bin/env/python3.x

However, I think this only works for Linux/Mac which it sounds like you aren't on if you're referring to cmd. You may want to check out this answer which has a few other options that may help: How do I tell a Python script to use a particular version

Alternatively you can set up a virtual environment, which allows you to run different versions of Python, modules and any other environment settings for a specific project. If that sounds like a better solution then this answer should help you out: (Easiest) Way to use Python 3.6 and 3.7 on same computer?

I used virtual environment way.Thanks for help. – Ömer Kenan Uçmaklıoğlu Mar 28 '19 at 17:25 — Ömer Kenan Uçmaklıoğlu, Mar 28 '19 at 17:25
