Despite the fact that you'll be able to develop functions within an interactive session, you’ll usually use the REPL for a person-line expressions and statements or for short compound statements for getting brief responses in your code.

Is that this a sound "easy" evidence that two free of charge teams are isomorphic if and provided that their rank is similar?

Copied! Digging into the code, you are able to see it starts by examining if num is fewer than 2. Prime numbers can only be better than or equal to 2. If num is a lot less than two, then the functionality doesn’t require to continue. It is going to print() a concept and return:
