Read password from stdin
Scenario: An interactive CLI Python program, that is in need for a password. That means also, there's no GUI solution possible.
In bash I could get a password read in without re-prompting it on screen via
read -s
Is there something similar for Python? I.e.,
password = raw_input('Password: ', dont_print_statement_back_to_screen)
Alternative: Replace the typed characters with '*' before sending them back to screen (aka browser' style).
>>> import getpass
>>> pw = getpass.getpass()
Yes, getpass
: "Prompt the user for a password without echoing."
Edit: I had not played with this module myself yet, so this is what I just cooked up (wouldn't be surprised if you find similar code all over the place, though):
import getpass
def login():
user = input("Username [%s]: " % getpass.getuser())
if not user:
user = getpass.getuser()
pprompt = lambda: (getpass.getpass(), getpass.getpass('Retype password: '))
p1, p2 = pprompt()
while p1 != p2:
print('Passwords do not match. Try again')
p1, p2 = pprompt()
return user, p1
(This is Python 3.x; use raw_input
instead of input
when using Python 2.x.)
