what exactly isn't working here

magic sinew Feb 2, 2026, 7:34 AM

#

!d any

crystal heartBOT Feb 2, 2026, 7:34 AM

any


any(iterable, /)```
Return `True` if any element of the *iterable* is true. If the iterable is empty, return `False`. Equivalent to...

have you learned about defining your own functions yet?

magic sinew Feb 2, 2026, 7:36 AM

#

tawny kraken have you learned about defining your own functions yet?

i havent heard of that yet

tawny kraken Feb 2, 2026, 7:36 AM

#

That's ok, Sacul has the right idea for it

#

Once you learn defining your own functions, this will be a great place to use it

ill keep an eye out for that in the future then if i see it in a video thank you

magic sinew Feb 2, 2026, 7:37 AM

rustic vapor Just do ⁨`while letter not in ('A', 'B', 'C'):...`⁩

would i put this above line 31

#

or alongside

tawny kraken Feb 2, 2026, 7:37 AM

#

Have you used while before?

magic sinew Feb 2, 2026, 7:38 AM

#

i have

tawny kraken Feb 2, 2026, 7:38 AM

#

It would go after getting input

magic sinew Feb 2, 2026, 7:38 AM

#

must i use it like i would any other then?

#

alright thanks

tawny kraken Feb 2, 2026, 7:38 AM

#

so you get input, and then the while loop would reprompt them if they entered something invalid

#

another common way to do it is just assign guess a dummy value first

#

guess = ''

#

and then only rely on the while loop for input

magic sinew Feb 2, 2026, 7:39 AM

#

alright thank you

magic sinew Feb 2, 2026, 7:44 AM

#

tawny kraken and then only rely on the while loop for input

is something like this alright?

#

i just went based off of a previous while true i used

tawny kraken Feb 2, 2026, 7:48 AM

#

magic sinew is something like this alright?

I think it's overengineered. The message appears again anyways from the input

#

guess = ''
while guess not in ('A', 'B', 'C'):
    guess = input("Enter (A, B, C): ").upper()

#

this is all it needs to be

magic sinew Feb 2, 2026, 7:51 AM

#

tawny kraken this is all it needs to be

i see

magic sinew Feb 2, 2026, 7:51 AM

#

tawny kraken ```py guess = '' while guess not in ('A', 'B', 'C'): guess = input("Enter (A...

this looks a lot better thank you
