added unwanted parenthesis for function parameters after completion

[wztdream]

Hi, I use python-language-server (pyls for short) as backend in emacs for python-mode. But it seems, pyls will insert an extra parenthesis for function parameters after completion.

It does not happens each time, seems only with some keywords, for example threshold_abs, distance ect. Any way, this behaviour is un-reasonable I have to delete the parenthesis each time, it is quite noisy.

Bellow is an example

from skimage.feature import peak_local_max
local_maxi = peak_local_max(distance, thresho|ld_abs=) ;; cursor behind 'o' marked by '|', then press Enter, it will be:

local_maxi = peak_local_max(distance, threshold_abs=()|)

Here is the log: request sending to pyls

[Trace - 04:32:53 下午] Sending request 'textDocument/completion - (1239)'.
