    Hello Joel,

                You can also use getpass() method to read the password, it
will not display the entered characters on screen.

import getpass
attempt=0
for attempt in range(3):
    pw=getpass.getpass()
    if pw=="unicorn":
        print "welcome in.. "
        break
else:
    print "That must have been complicated.. "
