But didn't it takes more time for slicing, if there is long list? And what if we check "len(arr) > 2" instead of "len(arr) > 1". Wouldn't it be faster?

i in this case would be the current element of the for loop not the list: for i in fruit_bag

i thought its possible to use "startswith" only with strings and not items in list ....

i'm not good at Python, but I dont understand how this could possibly be a problem. even if you do something like this:

def f(string):
  return string.upper()

import string
f(string = string.ascii_lowercase) # "ABCDE..."
string # <module 'string' ... >

there will be no issues. the only thing i can think of is if the user wants to use something from the string module inside of the function, and forgets to rename the parameter. i've changed it to strng just in case.

if someone sees a problem please reopen the issue

OP solved it, closing

You shouldn't close the issue before fixing it...

Oh, thank you for this comment. I saw in a lot of solutions this empty char put in front of the string and i was wondering if it is really necessary and if I missed something.

Sorry, i try to fix it

Kind regards

corrected

Don't mutate the input.

reversed(arr) actually returns an iterator, list(reversed(arr)) would create a list copy. Anyway, I think arr.reverse() is the fastest way to reverse a list https://stackoverflow.com/a/40294928/6260170

Got it, Example cases had a name string variable. Should work now.
