Python Main Function with Examples: Understand __main__
Python Main Function with Examples: Understand __main__
Like C, Python uses == for comparison while = for assignment. Python interpreter uses the main function in two ways
import: __name__= module’s filename
if statement==false, and the script in __main__ will not be executed
direct run:__name__=__main__
if statement == True, and the script in _main_will be executed
So when the code is executed, it will check for module name with “if.”
It is important that after defining the main function, you call the code by if__name__== “__main__” and then run the code, only then you will get the output “hello world!” in the programming console as shown below.
