Better code completion in python notebooks How come python code suggestion is awful in notebooks and spyder? Smetimes it shows classes methods and variables, sometimes not
If you are working locally (running e.g. starting up a Jupyter notebook from a terminal on localhost) code completiong should work just fine - I have never had any problems.

If you are running a Jupyter notebook attached to a Python process in a Docker container, there can be issues with code completion (the two-way communication may need to be activated).

You can try running the following ipython "magic command" that makes the interpreter greedy - this has worked for me in the past:

%config IPCompleter.greedy = True


Simply run that in the first Jupyter cell.

Here is a list of all built-in magic commands.

I am afraid I don't know of any differences in these cases between jupyter notebooks and Spyder.
