The main() is the entry point function which happens to be called first in most programming languages.
Since Python is interpreter-based, so it sequentially executes the lines of the code one-by-one.
Python also does have a Main() method. But it gets executed whenever we run our Python script either by directly clicking it or starts it from the command line.
We can also override the Python default main() function using the Python if statement. Please see the below code.
print("__name__ contains: ", __name__)
print("Testing the main function")
if __name__ == '__main__':
__name__ contains: __main__
