Hi all! I find very strange that the name of the file is changed automatically. What becomes the first name I gave to my file: about_main.py
I think buran is very well placed to answer this.

#about_main.py def funct(): print("Value of __name__ is: ", __name__) print('This statement is in main function') def someFn(): print ('This function is not called under the main function') someFn() if __name__ == "__main__": funct() """ Output This function is not called under the main functon Value of __name__ is: __main__ This statement is in main function ******************************************************* People use __name__ to determine if the script is being imported or not. If it's equal to "__main__" then it's not an import. The idea being, you want to run your main method if and only if you're not being imported. . *********** just to add to micseydel's answer. Given your sample code if you execute your script it will execute both functions (because of line 9 and line 11-12) if you import it in another script it will execute someFn (because of line 9) but will not execute the other one ******************************* yes, you can just call them. As to which is better - in my opinion it's better to get the habit of using if __name__ =='__main__': """
