Python Python Collections (2016, retired 2019) Slices sillyCase

hello, any ideas if the below code is not accepted as a correct answer? it seems to work as requested in "workspaces".

def sillycase(string): l = len(string) p=0 for i in string: if p < int(l/2): string[p] = string[p].lower() p +=1 else: string[p] = string[p].upper() p +=1 string = "".join(string) return string

sillycase.py
def sillycase(string):
    l = len(string)
    p=0
    for i in string:
        if p < int(l/2):
            string[p] = string[p].lower()
            p +=1
        else:
            string[p] = string[p].upper()
            p +=1
    string = "".join(string)
    return string

Are you sure this works in the workspace? In Python, strings are immutable, so it's not possible to change an individual character inside a string (as on lines 6 and 9). It also wouldn't work to "join" a string.

Are you perhaps missing a line of code that converted the string into a list?

you are absolutely right.... i have the following code in workspaces. i think i add it to the function, it should work :)

many thanks!!!! it was very frustrating.

str = input ("what is your string? ")

string=list(str)

p= sillycase(string)

print(p)

The list conversion needs to be done inside the function. Only the function code is needed (or used) in the challenge.
