remove last STDOUT line in Python

python stdout command-prompt

I am trying to figure out how to suppress the display of user input on stdout.

raw_input() followed by any print statement preserves what the user typed in. getpass() does not show what the user typed, but it does preserve the "Password:" prompt.

To fix this, I would like to only remove the last line (which would remove the newline from the end of the line as well).

You might be able to do what you want with VT100 control codes.

Something like this maybe:

CURSOR_UP_ONE = '\x1b[1A'
ERASE_LINE = '\x1b[2K'
print(CURSOR_UP_ONE + ERASE_LINE)
