grep capture python function definition

I have tried:

$ grep -Po "def[[:space:]]+\K(.*)\(" code.py

The output should be a list of function names.

I think it should be correct, but it's only capturing one extra bracket. I would like to get rid off it in the expression (not postprocessing). Please, explain the syntax, you will use.

You can omit the "(" from the resulting string by putting it in a lookahead (?=<expression>):

grep -Po "def[[:space:]]+\K(.*)(?=\()" code.py
