To my knowledge and extensive research on the problem, there is no simple way to disable python's welcome message: """ Python 3.7.2 (default, Jan 13 2019, 12:50:01) [Clang 10.0.0 (clang-1000.11.45.5)] on darwin Type "help", "copyright", "credits" or "license" for more information. """ It is appended to stdout before the execution of `PYTHONSTARTUP` and is very difficult to remove. This could be easily fixed by: 1. Allowing modification of the welcome message in `PYTHONSTARTUP` 2. Provide an option to disable it (IPython provides a `--no-banner` option to disable it) 3. At least provide a documented way of disabling it without hijacking the shell.
Yes, I forgot about that, but is there a way to edit it ? I just want to add a line after the first one to give system information. Disabling it and re-printing it seams a bit overkill and I don't want to alias `python` to `python -q`.
Why do you want to disable the welcome message? > I just want to add a line after the first one to give system information. Sounds like you just want to print something extra, after the welcome message has been printed.
