[split] Python Class Problem

[buran]

so a class is really a description of an object, true ?

yes - in general sense it's a "blueprint" of a thing. You can read more
https://en.wikipedia.org/wiki/Class_(com...ogramming)

so, for example, in this case it would make more sense if the class is named FileLoader (i.e. thing), than file_load (i.e. action)

and still i haven't understood why is it called a class...

what exactly worries you in class? Even outside of programming one of meanings of class is set or category of things having some property or attribute in common and differentiated from others by kind, type, or quality.
