[New-bugs-announce] [issue7963] Misleading error message from object(arg)

[Alexander Belopolsky]

New submission from Alexander Belopolsky <alexander.belopolsky at gmail.com>:

>>> object(1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: object.__new__() takes no parameters


This is misleading because object.__new__() takes one parameter:

>>> object.__new__(object)
<object object at 0x100413980>


I suggest changing "object.__new__() takes no parameters" to "object() takes no parameters".

Some other inconsistencies that I noticed:

>>> tuple.__new__(tuple, 1, 2, 3)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: tuple() takes at most 1 argument (3 given)

but

>>> list.__new__(list, 1, 2, 3)
[]
