Masking keyboard input with a character – Python version 3.0

Question

I want to mask my keyboard input with a character such as an asterisk on Python version 3 and above on a windows operating system,

I have this so far,

import getpass

pswd = getpass.getpass('Password:')

I can hide the password input, but I am not able to display a character for each individual letter

I tried using msvcrt module, but an error saying no module name ‘msvcrt’ keeps popping up, probably because i have Python version 3 and above. I also don’t want to use tKinter either.

I think I have just what you need.
Password is set to variable name ‘psw’.
This only seems to work in cmd though.

import msvcrt
import time
import sys
import os

def getPASS():
    print("Input password")
    list1 = []
    while True:
        char = msvcrt.getch()
        char =str(char)
        char = char[2:-1]
        if char == "\n'" or char == "\r":
            break
    elif char == "\x08":
        del list1[-1]
        os.system("cls")
        print("Input password:")
        sys.stdout.write("*" * len(list1))
        sys.stdout.flush()
        continue
    else:
        list1.append(char)
        sys.stdout.write("*")
        sys.stdout.flush()
print("n")
psw = "".join(list1)
print(psw)
invalid = ' ,:;/?"}]{[-=+!@#$%^&*()|'
for x in psw:
    if x in invalid:
        print("Character %r is not allowed in password" % x)
        getPASS()
    else:
        pass

getPASS()

Please give any improvements, Dan
