[Python Basics] About packages, classes, modules, and python

Before I understood python packages, classes, and modules, I always compared them to dll, C # classes, and namespaces, this is actually different from C #. Let's look at these units from a macro perspective.

_ Author _ = 'Bruce 'from Color. Red import DarkRedimport Humansif _ name _ =' _ main _ ': dark_red = DarkRed () dark_red.printinfo () pass

 

If you look at the segments, you will see: from Color. Red. Generally, the back of the from is directly followed by the upper-level space, and the import can only follow the first-level space.
