Question

What is the best way to get this block of code to run when I import main.py rather than run it?

#main.py
if __name__ == '__main__':
    #Do something interesting. 


#Do something to have the interesting code run after importing the file. 
import main.py
main.__main__() # wrong of course. 

Answer 1

Put that code into a function, and call it inside if.

def main():
    # ...

if __name__ == '__main__':
    main()

Or simply don’t use if at all.
