The variable __name__ is automatically set by Python, and it contains the name of the current module. If the script is being run as the main program, __name__ is set to '__main__'. If the script is being imported as a module, __name__ is set to the name of the module. Therefore, checking the value of __name__ is a good way to determine whether the script is being run as the main program or imported as a module.
