functools.partial wants to use a positional argument as a keyword argument

Question

So I am trying to understand partial:

import functools

def f(x,y) :
    print x+y

g0 = functools.partial( f, 3 )
g0(1)

4 # Works as expected

Not an answer, a follow up question (since I can't add a comment without 50 reputation), could you please elaborate or use simple terms as the answers here are above my comprehension. I have a similar issue using a button in Maya

import maya.cmds as cmds
from functools import partial

class Myclass(object):
    def __init__(self):
        pass
    def createui(self):
        derp = cmds.window()
        cmds.formLayout()
        cmds.button(label = "w/e", c = partial(self.f, x = 3))
        cmds.showWindow(derp)
    def f(self, x = 5, y = 3, *_):
        print(x+y)

herp = Myclass()
herp.createui()

clicking on the button will give that same error "got multiple values for keyword argument 'x'"

even though what I thought was being sent as arguments was a call to the class, some stupid call to the UI element itself (usually a value of False) which should be put in the *_ catch all argument, and then keyword argument of x.
