string.split() documentation incorrect?

[Jerry Seutter]

I'm trying to use string.strip to remove the comma off the end of 
a string, eg:

string.strip("id INT NOT NULL,", ",")

The current documentation says I can do this.  Python 2.2.2 gives
the following error:

>>> strip('  hello  ', ',')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: strip() takes exactly 1 argument (2 given)

So, I think either the documentation is incorrect or there is 
a bug.  Thoughts?
