1. My code has a bug, why the door to guess passwords 11 times instead of 10 times?

A: As in vitro cycle has had a line input-12, as follows:

11　　　　　 code = "%d%d%d" % (randint(1,9), randint(1,9), randint(1,9))
12　　　　　 guess = raw_input("[keypad]> ")
13　　　　　 guesses = 0
14
15　　　　　 while guess != code and guesses < 10:
16　　　　　　 print（"BZZZZEDDD!"）
17　　　　　　 guesses += 1
18　　　　　　 guess = raw_input("[keypad]> ")

So if you do not enter only use 10 times, then you need to change the judgment conditions are as follows:

11　　　　　 code = "%d%d%d" % (randint(1,9), randint(1,9), randint(1,9))
12　　　　　 guess = raw_input("[keypad]> ")
13　　　　　 guesses = 0
14
15　　　　　 while guess != code and guesses < 9:
16　　　　　　 print（"BZZZZEDDD!"）
17　　　　　　 guesses += 1
18　　　　　　 guess = raw_input("[keypad]> ")
