Difficulty with Challenges

My way to solve problems is to think: "How would I do this manually in real life?"

For example, if your challenge is to reverse a string, I think to myself, "How would I do this step-by-step on my own?" There are several ways to do this manually, but my preferred way is to imagine two strings: the one you are reversing and the one you want to be the result (aka the new reversed string).

On the first "step", you take the first letter of the first string, and append it to the end of the second string. Then you take the second letter and repeat, then the third, etc. The You repeat the process until the second string is done, then you return it.

It should be apparent that a loop is needed. (Notice the word "step")

def reverse(string):
    new_string = ''
    for i in range(len(string)):
        new_string += string[i]
    return new_string

This way of solving problems usually works for most basic problems.

Eventually, when you do a lot of these kind of problems, it starts to get easier because you've seen many kinds of problems. It is expected to be difficult at first, though. You are doing excellent! Keep on learning and good luck
