Passing more arguments to this type of python function

Question

I figure this is pretty basic, but can\'t seem to figure out even how to ask google the right question. I am using this python websocket client to make some websocket conne

Answer 1

You can use a lambda to wrap the call:

ws.on_open = lambda *x: on_open("this new arg", *x)

Answer 2

Keep in mind that you need to assign a callback. You are instead calling a function and passing the return value to ws, which is incorrect.

You can use functools.partial to curry a function to a higher order one:

from functools import partial

func = partial(on_open, "this new arg")
ws.on_open = func

When func is invoked, it will invoke on_open with the first argument as "this new arg", followed by any other arguments passed to func. Look at the implementation of partial in the doclink for more details.
