Here are small things that might improve your program:
The whrandom module has a function called "choice()" which lets you grab
at a random element out of a list. So, instead of:
you could use:
which is a bit nicer to read. whrandom.choice() works on strings as well
as lists, so its a nice function.

Creating a function that does the replacement would be nice. Here's
# Let's first make str a mutable list.
# The reason for this is because we can modify a
# list "in-place".
templist = list(str)
# Time for the replacement stuff
for i in range(len(templist)):
if templist[i] == '.":
templist[i] = whrandom.choice(vowels)
# skipping consonant stuff
# finally, bring the list back as a string:
return string.join(templist, "")
So the loop goes through each character on your list, but you only do
something if that character is a '.' or a ','. I haven't tested the code
above yet, but I hope that it makes sense.
