Can you please give me some insight?
Others have told you how to fix it. The insight is that when
you import a python file its __name__ attribute is set to the module
name. When you run it as the top level script its __name__ is set to
__main__.
So you want to create an 'if' test, and it can be anywhere in your code
there is nothing special about it, but usually it's at the bottom of the
file and looks like:
def moduleFunc()
# this is the code that gets used as a module
def anotherFunc():
#and so is this
def main():
# put your main program code here
# it doesn't get run if the file
# is imported
# - unless the user chooses to explicitly of course!
if __name__ == "__main__":
main()
# or call it test() if the file is only expected to be used as a module
