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