[New-bugs-announce] [issue9943] TypeError message became less helpful in Python 2.7

[Geoffrey Bache]

New submission from Geoffrey Bache <gjb1002 at users.sourceforge.net>:

Consider the following code:

### keywords.py

def f(**kw):
    print arg, kw

f("hello", keyword=True)

and compare the behaviour in Python 2.6 and Python 2.7:

$ python keywords.py 
Traceback (most recent call last):
  File "keywords.py", line 5, in <module>
    f("hello", keyword=True)
TypeError: f() takes exactly 0 non-keyword arguments (1 given)

$ python2.7 keywords.py
Traceback (most recent call last):
  File "keywords.py", line 5, in <module>
    f("hello", keyword=True)
TypeError: f() takes exactly 0 arguments (2 given)

The error message from 2.6 is I would say a more accurate description of the situation.
