Intellisence for common languages would be nice

I had emacs turned on from a while ago and i didn't notice.

How can't you? Can't you select the code and copy it? What code you mean, the one in editor, or on some list of solutions?

What's stopping you from doing that?

It is extremly annoying that you can't copy and paste even the code you have already written.

How do you follow someone? I can't search for users

If that's for some kata, I suggest you use that kata's Discourse to ask your question, read this

Here it's unrelated and hard to reply without context.

class Addition:
pass

def add(a, b):
    c = int(a) + int(b)
    return c

a = Addition()

print (a.add(5,6))

I am trying to run above code but getting error that
"add() takes 2 positional arguments but 3 were given"

Can someone please help where am I making mistake?

All suggestions should be made on CW github.

It would be cool if you could filter out the passed or the failed test results.
