How do I tell a python script to execute a particular python version in python script

Question

My Jenkins is using python 2.7 to execute python scripts. But I want to execute the script using python 3.7. So far I have done something like this.

test.py

#!/home/sam/python/python3/bin/python3.8
import sys

print(sys.version)

I am executing this script with python test.py. In output I am getting python version 2.6. Can anyone suggest how can I run the python script with python 3.7 path.

The shebang will only be honored if the script is launched like test.py, and NOT python test.py. You need to use python3 test.py (or /full/path/to/python3 test.py). — 0x5453

If you want to select versions per command, you can use command line options like these:

py -2 my_file.py
py -3 my_file.py
py -2.7 my_file.py
py -3.4 my_file.py
