python conditional statement

def authentication(password):
    if password == 'unstoppable':
        message = "Login Successful !! Welcome to the Softhunt"
    else:
        message = "Try a different password"
        
    return message
    
def main():
    print("Authentication System")
    print("======================")
    passwordInput = input("Enter your password: ")
    checkPass = authentication(passwordInput)
    print(checkPass)
main()

num = 1

if num == 1:
   print("num is 1"))
elif num == 2:
   print("num is 2")
else:
   print('invalid number')
# output num is 1

# if the conditional is true the left side of side the expression is resolved else the right side is resolved
print("num is 2") if num == 2 else print("num is 1")
# output num is 1
