Problem Description

When using the ipython console, and I use tab completion in a list comprehension, the preceding object/module is removed and the method is completed.

What steps reproduce the problem?

1. import math
2. test = [math.<tab>
3. math is removed and line shows as test = [.; completion dialog opens.
4. When completion option is selected, e.g., acos, the line becomes test = [.acos

What is the expected output? What do you see instead?

I expect to see test = [math.acos(. Note that this appears to only be a problem with the ipython console; the editor behaves as expected.

Hi @evanhorn thank you for the feedback! I think I was able to reproduce this! Just in case a preview of the issue:

interestingly, the issue doesn't happen when using QtConsole 🤔 :
