Why not just use * instead of + like:
if re.search(r'^[^LRM]*$', var): # note: ^ outside [] is start of

This will *only* print invalid when there is a character other than L,
R, or M or a empty string.
Sorry, forge

How about skipping re's and doing something like:
set(input_string) <= set('LMR')
If you want to disallow the empty string:
set([]) < set(input_string) <= set('LMR')

Hi,
Hi,
I am taking a string as an input from the user and it should only
contain the chars:L , M or R
I tried the folllowing in kodos but they are still not perfect:
[^A-K,^N-Q,^S-Z,^0-9]
[L][M][R]
[LRM]?L?[LRM]? etc but they do not exactly meet what I need.
For eg: LRLRLRLRLM is ok but LRLRL
