Answer 1

This is not recursion, this is an endless loop.
Recursion needs an exit condition.

Answer 2

Tibor Santa I disagree. It is recursion wrongly executed. It becomes an endless loop. Recursion is a function calling itself. Obviously when using recursion you always need an exit otherwise you end in an endless loop like this case.

Answer 3

GeraltdeRivia ok, you are right of course ;)

Kath have you figured out yet?
There is actually a very easy way to reverse a string that doesn't involve recursion, only list slicing:

text = 'hello'
print(text[::-1]) # olleh

Answer 4

the underlying problem is that there's nothing blocking it from recursion ( it keeps calling itself until it exceeds its limit ).
so one way to fix this is that you have to add what's called the base case.
