[...] Similarly, if you wanted p1==p2, why not write

p1 = partial(operator.add) p2 = p1 I thought the OP gave a use-case. He's generating "jobs" (partial applied to a callable and arguments), and wanted to avoid duplicated jobs. I think it is reasonable to expect that partial(operator.add, 2) compares equal to partial(operator.add, 2). I don't think he's suggesting it should compare equal to partial(lambda x,y: x+y, 2). Which absence, presumably, also mildly disappoints you?

it disappoints me this does not compare equal:

add3 = lambda a, b, c: a + b + c a = partial(partial(add3, 1), 2) b = partial(partial(add3, 2), 1) print a == b
