The code completion in the editor is not working

Description

What steps will reproduce the problem?

1. type “import os”
2. type long_name_for_completion = 1
3. type long_name, press tab (or control + space), nothing happens.
4. type os., press tab, nothing happens.

What is the expected output? What do you see instead? There should be a list of possible variable names for me to choose when I press tab.

Please provide any additional information below It works in the IPython console, but not the editor.

Actually one hour ago it works well in the editor. Just after a dinner it is not working. I’ve tried reinstalling spyder, rebooting, updating the packages, etc. It still doesn’t work.

Following issue #5782 for spyder=3.2.6 and python 3.6.3 Anaconda, Windows 8.1 x64:

pip uninstall enum34 restarting spyder

was able to solve my problem with missing autocomplete.

@EonSin Thanks a million for the hint with enum34! I uninstalled it with pip and code completion works perfectly after restarting spyder.
