How did I get informations on the module I'm writing?

Question

I'm writing my first complete python project with Vim. As I was modifying a file I accidentally hit several keys that I can't find back and I get this prompt:

I didn't know it was possible to get this kind of help on a module I am writing and I have no idea how I got it, so my question is:

What command or tools allows to generate this kind on module information?

Several notes

• The command is not a Vim command because the ouput was in an external shell (so I probably use an equivalent to :![command].

• I don't have any Vim plugin related to python installed so it was probably not generated by a plugin.

• The command wasn't issued in an interactive python prompt since I started my vim from my bash prompt.

• I have not idea of how many keystrokes I used.

• My Vim command history and my bash history doesn't have a trace of what happened.

• I'm using zsh and oh-my-zshell

I know that this question might sound silly but I have no idea of which tool can do that and I have no mean to find what sequence of keystrokes I used.

You can use pydoc command to get module help

pydoc requests

if you are using the interactive python shell, you can use the help function:

>>> import requests
>>> help(requests.get)

it work on class instance too
