What does Copy () do in Python

Answered By: Hugh Cook Date: created: Jun 19 2022

The copy() method in Python returns a copy of the Set.

We can copy a set to another set using the = operator, however copying a set using = operator means that when we change the new set the copied set will also be changed, if you do not want this behaviour then use the copy() method instead of = operator..
