Run Python module in another code but with an older version

Question

I am using Python 3.10 but I want to run a Python module with Python 3.6 and use the result inside my code(that written with Python 3.10)

Please help me to solve it
thanks

Answer 1

1. Create a .py script that should be run with python3.6
2. Make the script prints your expected result

# script.py
import sys

print(sys.version[:6])

3. Use subprocess to get it

import subprocess

python3_6_result = subprocess.check_output(["python3.6", "script.py"])
print(python3_6_result) # 3.6.15
