How to use one = with multiple and/or

Question

while party!='R' and party!='D':

can this be shortened to

while party!='R' and 'D':

while party!=('R' and 'D'):

or the like? (that is, is there any equivalent expression with only one party!=)

Answer 1

If you want to use multiple condition:

try this.

l=['R','D']
while party not in l:

Answer 2

you can simply create list and use like this

validList = ['R', 'S']
# You can also use not in operator for other condition
if party in validList:
    # Do your stuff here
    print("It's Present")
