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.

usr = getpass.getuser()

pwd = getpass.getpass("enter password for user %s: " % usr)

print usr, pwd
