Python Functions and OOP

Question

Hello,everyone

So,I am in need of a idiot-proof explanation about Function. I mean,i get the core idea,functions are basically a mean to give functionality to an expression using blocks of code which can be reused for better writing,analysis,debugging and overall efficiency. but I don't get the 'reverse value',being called' definitions. Dunno if it's because I'm not fluent in English,but theses therms are rather vague for me.

If someone can explain to me ( I really appreciate examples ),I would be really grateful

Good d/a/n
