Import a script python

Question

Does the <<if __name__="__main__":>> , import a python script and if why does it swap the if and else conditioned statements

Answer 1

No. that statement does not import any script.

it is a test case to see if the current script is being runned directly OR being imported.
if it is being runned the special variable __name__ will have value '__main__', this means that what come after the if will be executed
if it is being imported, what comes after the if will not be executed.

Its a Python trick.
