We're making blackjack and when we ask hit or stay, how do we make sure that the player gives us a valid response by typing either 'hit' or 'stay'?
You could assign numbers as responses. Like press 1 to hit and 0 to stay.
def call(): stand = input("Press '1' to STAY or '0' to HIT") if stand == 1: do something elif stand == 0: do something else else: call()
If you are using python 3 then the above code will not work. What you will need to do then is slightly different as
input() in python 3 returns a string.
choice = input("Press 1 to hit or 0 to stay") if int(choice) == 1: print "Lets hit it!" elif int(choice) == 0: print "nothin doing"
Hope that helps :)
response = input("Hit or stay: ").lower() if (response != "hit") and (response != "stay"): #bad response pass else: #good response pass
the above post might not work since if the user types something other than number,
int() won't work, and there will be an exception.
