What Does if __name__ == “__main__”: Do in Python?
The line if __name__ == "__main__":
is used in Python to check whether the current script is being executed as the main program or it is being imported as a module into another program.
If the script is being run as the main program, then the code inside the if
block is executed. On the other hand, if the script is being imported as a module, the code inside the if
block will not be executed.
This allows you to differentiate between the behavior of a module when it is run as the main program or when it is imported into another program.
