Anaconda does not retrieve signatures for certain functions, even though jedi does

[dalanicolai]

While trying anaconda-mode, I've noticed that it does not retrieve signatures for certain functions. Specifically, I was testing with the following code

import os

os.getenv()

print()

Anaconda mode does retrieve a signature when the cursor is between the parentheses after print, but it does not retrieve the signature when between the parentheses after os-getenv.

Using the jedi api from a terminal, jedi.Script.get_signatures does retrieve signatures for the latter position. Also, does jedi.el.

I could not find a reason for this behavior, also I could not debug it easily. Therefore I am creating this issue.

For completeness, I only see a *anaconda-mode* buffer which contains only the line anaconda_mode port 38419. Also, I am using python version 3.11 (but I think I have also tested it with version 3.9).

Thank you for this otherwise great package!

I have found the culprit. The problem is that the eldoc function in anaconda-mode.py only returns signature data when len(signatures) == 1, while for os.getenv() the length == 2. It would be nice to show both signatures with eldoc.
