python - "GetPassWarning: Can not control echo on the terminal" when running from IDLE

When I run this code:

import getpass

p = getpass.getpass(prompt='digite a senha\n')
if p == '12345':
    print('YO Paul')
else:
    print('BRHHH')
print('O seu input foi:', p) # p = seu input

I got this warning:

Warning (from warnings module):
   File "/usr/lib/python3.4/getpass.py", line 63
    passwd = fallback_getpass(prompt, stream)
GetPassWarning: Can not control echo on the terminal. Warning: Password input may be echoed.

That would be system and terminal-dependent: docs.python.org/2/library/getpass.html Prompt the user for a password without echoing. ... If echo free input is unavailable getpass() falls back to printing a warning message to stream and reading from sys.stdin and issuing a GetPassWarning. - handle
I think the warning is telling you precisely that there is not a way (that Python knows or recognizes) to prevent the password from being echoed on the system where the message is emitted. - John Bollinger

IDLE interferes with normal console input & output; getpass was not designed to be used in such environments. - PM 2Ring

Use an actual terminal -- that is, an environment where stdin, stdout and stderr are connected to /dev/tty, or another PTY-compliant device.

The IDLE REPL does not meet this requirement.

Run your code in terminal, instead of the IDE. you will see that there is no more warning there. To run your code, enter this command in terminal:

python3 your_program.py

Rather than deal with changing the current working directory in a terminal that has not started Python (which would mean you type something like python3 script.py--and it will fail unless the current working directory is already specified), start Python in your terminal and run this one-line command:

exec(open('C:\folder\script.py').read())

where you change the path string 'C:\folder\script.py' to match wherever your file is located on disk (the string does need to be specified with quotes).

use cmd ie. command prompt and then run the file in it.

like:

python abc.py
