Why would we use dunder main? Just don't import the file? I'm confused.

Kind of confused, if we don't want a certain file to be run, then don't import it in the first place.

What am I missing here? 😅

Hello! You will eventually build more complex programs that require you to import different scripts you wrote. Using main enables to have control over how everything is run and is a good practice for others to understand your code. Hope this helps!

when expand the level of your project this will become much more obvious and very helpful this actually important in the important in the functionality and popularity just look at already available python libraries that you can import such as math which was shown in the first course and such as numpy and pandas which is why python is so popular in the datascience field.
