How do I convert a password into asterisks while it is being entered?

Question

Is there a way in Python to convert characters as they are being entered by the user to asterisks, like it can be seen on many websites?

For example, if an email use

Answer 1

For anyone who would actually want to have asterisks appear, here's an improvement on Tigran Aivazian's answer. This version imports the built-in msvcrt.getch, adds cases for different line endings when hitting 'Enter/Return', and includes logic to support Backspace, as well as Ctrl+C (KeyboardInterrupt):

try:
    from msvcrt import getch
    def getpass(prompt):
        """Replacement for getpass.getpass() which prints asterisks for each character typed"""
        print(prompt, end='', flush=True)
        buf = b''
        while True:
            ch = getch()
            if ch in {b'\n', b'\r', b'\r\n'}:
                print('')
                break
            elif ch == b'\x08': # Backspace
                buf = buf[:-1]
                print(f'\r{(len(prompt)+len(buf)+1)*" "}\r{prompt}{"*" * len(buf)}', end='', flush=True)
            elif ch == b'\x03': # Ctrl+C
                raise KeyboardInterrupt
            else:
                buf += ch
                print('*', end='', flush=True)
        return buf.decode(encoding='utf-8')
except ImportError:
    from getpass import getpass

Please feel free to suggest any other changes, or ways to improve this; I hacked the changes together pretty quickly, especially with the Backspace logic.
