can you explain your solution?ty

In terms of time complexity, using count() is not very efficient because for each character in the string, you are iterating through the entire string again to count its occurrences.

Good job! :)

yea I thought how could I count them(not knowing there is also count function lol

I was trying a similar approach but I wasn't sure how to say if there were a repeated character.
The if stament is pretty clever.

clean, but, in my opinion too hard

Clean and readable.

LOL, I do the same

Same.

I have to remember these functions so I can have cleaner code

like Orange once said: sounds great doesn't work

Since string is a standard module, it should not be used as a variable name, no?

why can't i use the lower() in the for statement?

I mean: string = string.lower() -> for letter in string.lower()

I have tried but doesn't work and i don't know why.

Thanks
