i'm unable to add more exceptions to this script

Question

how can i add more exceptions to this script?
i want to have more than "admin" as prohibited
i tried or but it didn't work

print('''
Welcome to program
Please enter your Username
''')

username = input("Your username is :\n")

if username == "admin":
print("Please choose another username for the program")
username = input()
elif username != "admin":
print(username, ", welcome to our program!")

Answer 1

if username == "admin" or username == "something_else":

...should work fine.

Alternately, if you want even more:

if username in ("admin", "something_else", "another_name", ...):

would work too.

Answer 2

yeah it is working thank you so much
