Question

I searched on google how that iter() and next() do in python after seeing it in a challenge on python but i still dont get it

Answer 1

an iterator is an object used to iterate across iterable objects such as lists, tuples, dicts, and sets.

the iter() method is used to initialize the iterator object.
iteration is accomplished through the usage of the next() method.

don't forget about generators while you are learning about iterable objects.
here is a good explanation in SO

Answer 4

What i understand that you copie the iterable objects in variables like (iterator=iter(name)) than you choose one character of the variable using next()
