Think what happens if after the third pass the password is still wrong:
The loop looks in the condition: password != "nabbers!" which is true,
so the loop starts a new cycle; count is bigger than three so it jumps
directly to the else part, prints its message and starts a new cycle ...
So you have to find a way to break the loop unconditionally: if you only
wanted to stop the loop `break' would be right, but you also want to
stop the programm; for that you could use a method from the sys module:
You could write:
count = 0
password = ""
while password != "nabbers":
if count < 3:
password = raw_input("Password: ")
count += 1
print "Too complicated, huh?"
print "Welcome inside."
