The documentation for random.uniform() was recently updated to reflect 
the fact that it's possible for random.uniform(a, b) to produce the 
value b;  see issue 4979.

In a recent c.l.p. thread, Robert Kern suggested that 'it 
might be confusing to a user why random.random() returns values in a 
half-open interval while random.uniform() claims a closed interval';  
the thread itself confirms this potential for confusion.  See

http://mail.python.org/pipermail/python-list/2009-June/715851.html

Suggested extra wording for random.uniform, from Robert Kern:

"Due to floating point arithmetic, for some values of a and b, b may or 
may not be one of the possible generated results."

Regardless of whether the extra wording is added or not, the docstring for 
random.uniform should probably be changed to match the online 
documentation.  It currently says:

"""Get a random number in the range [a, b)."""

That should probably be:

"""Get a random number in the range [a, b]."""

Right.
