Using IPython on my linux terminal (Debian), I would like to see the function signature (arguments and docstring) when I press ( after the function name, in a popup.

Notes:

  • function_name? works.

  • I'm sure that program actually sees the function data, since when I write pd.DataFrame(col<Tab> it autocompletes with columns=, an argument of pd.DataFrame.

  • I already tried Tab and S-Tab without success.

    I'm not familiar with a way to do it, this is a good question. Note - it works on qtconsole, under the hood, it calls inspect. Also - after setting %config IPCompleter.use_jedi = False I get the list of arguments when pressing tab after function_name(. Commented Feb 20 at 15:47

  • @idanp yes, by turning off jedi I can now see at least fun arguments, so this is definitely an improvement. But not the docstring of the function and the rest of useful stuff shown with ?. Commented Feb 20 at 16:06
