python - Why does this programme not stop after three password guesses? - 


username = "patrick"  password = "kearney"    username = input("username:")  while username != "patrick":      print("please try again.")      username = input("enter username again.")   password = input("password:")  incorrect = 0  threshold = 3  while password != "kearney":          print("please try again.")          password = input("enter password again.")  if password != "kearney":          incorrect += 1 else:         print("welcome patrick")         incorrect = 0   if incorrect == threshold:          import sys          sys.exit()

for if executed inside while loop, should indent properly, should work:

username = "patrick" password = "kearney"  username = input("username:")  while username != "patrick":     print("please try again.")     username = input("enter username again.")  password = input("password:") incorrect = 0 threshold = 3  while password != "kearney":     print("please try again.")     password = input("enter password again.")     if password != "kearney":         incorrect += 1     else:         print("welcome patrick")         incorrect = 0      if incorrect == threshold:         import sys         sys.exit()

edit: @benjamin pointed out in comments going allow 4 trials (1 outside while loop , 3 inside loop), set threshold 3 or incorrect 1 @ beginning fix this.
