# 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 somethingif __name__=='__main__':
basically, (__name__ == '__main__') ==True
confirms file is NOT a/part of a module and may continue execution #This is a way of executing your code if it runs directly from your system.
#This means that your code was not 'imported', but executed directly.
if __name__ == "__main__":
#execute my code...# The code in this 'if' statement runs only if current file is the
# the main file. Mean this if statement code will not run if you import
# that file into other program.
if __name__ == '__main__':
