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. |
