Summary: Poor error message for float()

Initial Comment:
This line of Python (2.2):

    x = float([0])

gives the error:

    TypeError: float() needs a string argument

But since "float(0)" is OK, a better error message
might be:

    TypeError: the argument of float() must be a string
or a number

I use RedHat 7.1 Linux on a PC.

This has been fixed for Python 2.3 which now says:
TypeError: float() argument must be a string or a number.

Will look at backporting to a maintenance release of Python 
2.2.
