    def getpass(prompt):
        """Replacement for getpass.getpass() which prints asterisks for each character typed"""
        print(prompt, end='', flush=True)
        buf = ''
        while True:
            ch = getch.getch()
            if ch == '\n':
                print('')
                break
            else:
                buf += ch
                print('*', end='', flush=True)
        return buf
except ImportError:
    from getpass import getpass
