Stop execution of a script called with execfile

Question

Is it possible to break the execution of a Python script called with the execfile function without using an if/else statement? I\'ve tried exit(), but it doesn\'t a

Answer 1

# script.py
def main():
    print "Script starting"
    a = False

    if a == False:
        # Sanity checks. Script should break here
        #     
        return;
        # I'd prefer not to put an "else" here and have to indent the rest of the code
    print "this should not print"
    # lots of lines bellow

if __name__ ==  "__main__":
    main();

I find this aspect of Python (the __name__ == "__main__", etc.) irritating.
