How do you exit a python program without the error statement?

Question

How do you quit or halt a python program without the error messages showing?

I have tried quit(), exit(), systemexit(), raise SystemExit, and others but they all seem to raise an error message saying the program has been halted. How do I get rid of this?

Answer 1

You are trying too hard. Write your program using the regular boilerplate:

def main():
    # your real code goes here
    return

if __name__ == "__main__":
    main()

and just return from function main. That will get you back to the if-clause, and execution will fall out the bottom of the program.

You can have as many return statements in main() as you like.
