Python Sort() method

Question

I am starting to learn Python.

Can someone explain why sort() returns None?

alist.sort()            ## correct
alist = blist.sort()    ## NO incorrec         


        

Answer 1

Answering to his question, it returns none because the method always returns None. When you use it, it automatically modifies the list, so it does not keep the original intact (ie it does not return a sorted copy of the list).
