I don't. Trust me on this, you will regret it. As the Zen of Python says, "Explicit is better than implicit". It may seem like a good idea now, but some day you'll write code like this:


def reward(msg):
     print(msg)
     if 'link' in msg:
         administer_electric_shock()
     else:
         give_cake()


def administer_test(username):
     score = 0
     for question, answer in list_of_tests:
         response = input(question)
         if response == answer:
             score += 1
     if score > len(list_of_tests):
         msg = "Congratulations %s, you have passed!" % username
     else:
         msg = "%s, you are the weakest link!" % username
     reward(msg)


Can you see the bug?
