In section 2.3, 'Built-in Functions', I think the 
following description for 'apply' is incorrect:

"The function argument must be a callable object (a 
user-defined or built-in function or method, or a 
class object) and the args argument must be a sequence 
(if it is not a tuple, the sequence is first converted 
to a tuple). "

I suggest the following:

"The function argument must be a callable object (a 
user-defined or built-in function or method, or a 
class object) and the args argument must be a tuple 
(if it is a sequence, the sequence is first converted 
to a tuple)."

I found this in the Release 2.1 beta 1 version of the 
Python documentation at:

On further review, this is better:

"The function argument must be a callable object (a 
user-defined or built-in function or method, or a 
class object) and the args argument must be a tuple or a 
sequence (if args is a sequence, apply converts the 
sequence to a tuple)."

Suggestion declined:  because non-tuple sequences are
automatically converted to tuples, it makes no sense to say
that 'args' must be a tuple -- any sequence will do.
