Note that there's a subtle difference to make here. IMHO as soon as you use terms like "receives" or "accepts", you are still talking about arguments. What you pass from one side is received by the other, and it's called an argument. Given "def f(x, y): pass" you can say that x and y are parameter of the f function, or that the function accepts 2 arguments -- x and y. The latter is far more common IME, and I rarely talk about parameters myself. In "f() missing 1 required positional argument: 'x'", the usage of "argument" is correct, because what's missing is the argument in the function call, not the parameter in the function definition. However the error points to the corresponding parameter 'x' -- because clearly it can't point to the argument you forgot to pass -- and this fact might led to some confusion. IMHO though, the error is clear as is (at least regarding argument/parameter), so I wouldn't change it. ---------- nosy: +gvanrossum _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15990> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
