I am getting as such error for executing my hello world program:
\"This file does not have a program associated with it for performing this action\"<
1) Download the official version of Python
2) Use custom installation following the screenshots bellow.
3) Run your hello.py
file directly from the command line by typing hello.py
from datetime import datetime
print("\nHello World\n",datetime.now().strftime("\b%m/%d/%Y\n%H:%M:%S"))
