python if __name__ == __main__ not running file code example
Example 1: __name__== __main__ in python
# If the python interpreter is running that module (the source file)
# as the main program, it sets the special __name__ variable to have
# a value “__main__”. If this file is being imported from another
# module, __name__ will be set to the module’s name.
if __name__=='__main__':
# do something
Example 2: python if name == main example
# It's as if the interpreter inserts this at the top
# of your module when run as the main program.
__name__ = "__main__"
