**** PassWord

[nilamo]

getpass is a module in the standard lib, it is 100% python code.  Here's the source: https://github.com/python/cpython/blob/3...getpass.py

It uses getch, which gets a single character from input instead of a whole line.  In order to do so without also echoing what you type, it uses a different method depending on your operating system.  So, I copied a lot of that, and changed it a bit to ALSO echo out an asterisk while waiting for input.

import sys

def _find_getch():
    try:
        import termios
    except ImportError:
        # Non-POSIX. Return msvcrt's (Windows') getch.
        import msvcrt
        return msvcrt.getch

    # POSIX system. Create and return a getch that manipulates the tty.
    import tty
    def _getch():
        fd = sys.stdin.fileno()
        old_settings = termios.tcgetattr(fd)
        try:
            tty.setraw(fd)
            ch = sys.stdin.read(1)
        finally:
            termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
        return ch

    return _getch

getch = _find_getch()

pword = ''
ch = 'spam'
# keep looping until "enter" is hit
while ch not in '\r\n':
    ch = getch().decode()
    pword += ch

    print('*', end='')
    # we need to flush, or else the asterisks won't appear
    # until after the password is finished getting entered
    sys.stdout.flush()
# add a newline after the asterisks
print()

# prove that we actually got something
print(pword)
