InteractiveShellApp.banner1

## The part of the banner to be printed before the profile
#  Default: "Python 3.9.0 (default, Nov  2 2020, 18:14:37) \nType 'copyright', 'credits' or 'license' for more information\nIPython 7.19.0 -- An enhanced Interactive Python. Type '?' for help.\n"

You can customize the banner that is displayed on startup-- if you’re the kind of person who likes to tweak every customizable aspect of a system. You could cut it down to the important bits if you are into the whole brevity thing: ³

c.InteractiveShell.banner1 = "Python 3.9.0 -- IPython 7.19.0\n"

…or eliminate it entirely:

c.TerminalIPythonApp.display_banner = False

^{3. Yeah? Well, you know, that’s just like, uh… your opinion, man. ↩}
