See more:

def reverse(text):
    reversed_string = ("")
    for letter in range(0, (len(text)), -1):
        reversed_string += str(letter)

print(str(reversed_string))

When I print this, it says reversed_string is not a defined variable.

What I have tried:

I have tried using string methods such as str(), I have tried deleting the variable and making a different, I have tried pretty much everything.

Solution 1

In this case the variable reversed_string is only known within the bounds of the reverse function. You need call reverse with a string as an argument e.g.

Python

print( reverse("Hello World!") )

But in order for that to work you'll need return reversed_string before exiting the reverse function.

Then you will have to figure out why your reverse function returns None.

Sorry, I'm stupid. I'm trying to make this code without using the reverse/reversed function and without using [::-1]

In this case the reverse() function would be the function you supplied a def for. Suppose instead of def reverse(text): you had declared def myreverse(text):, then you would call print( myreverse("Hello world!") to get the output you want.
