Here's a function that prompts for a password with echoing turned
off. Note the technique using a separate
<tt class=
"function">tcgetattr()
</tt> call
and a
<tt class=
"keyword">try
</tt> ...
<tt class=
"keyword">finally
</tt> statement to ensure that the
old tty attributes are restored exactly no matter what happens:
<div class=
"verbatim"><pre>
def getpass(prompt =
"Password: "):
old = termios.tcgetattr(fd)
new = termios.tcgetattr(fd)
new[
3] = new[
3]
& ~termios.ECHO # lflags
termios.tcsetattr(fd, termios.TCSADRAIN, new)
passwd = raw_input(prompt)
termios.tcsetattr(fd, termios.TCSADRAIN, old)
