def partial(func, args, *keywords):

def newfunc(*fargs, **fkeywords):
    newkeywords = keywords.copy()
    newkeywords.update(fkeywords)
    return func(*(args + fargs), **newkeywords)
newfunc.func = func
newfunc.args = args
newfunc.keywords = keywords
return newfunc

The code in the python standard library, please ask
newfunc.func = func
newfunc.args = args
newfunc.keywords = keywords
These three sentences seem to be of no use?
