Having seen this bite someone recently, I have an example readily at hand:
>>> def f(a,b,c,d=None): pass
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: f() takes at least 3 arguments (3 given)
The mention of self might be a bit of a red herring, since unless
there's another way to generate the same error message, the error
really is "f() takes at least 3 arguments (2 given, plus 1 keyword
argument not counted here)".
