The getpass Module
The getpass module provides a platform-independent way to enter a password in a command-line program, as Example 2-25 shows.
getpass(prompt) prints the prompt string, switches off keyboard echo, and reads a password. If the prompt argument is omitted, it prints "Password:".
getuser() gets the current username, if possible.
Example 2-25. Using the getpass Module
File: getpass-example-1.py
import getpass
usr = getpass.getuser()
pwd = getpass.getpass("enter password for user %s: " % usr)
print usr, pwd
enter password for user mulder:
mulder trustno1
