It's possible, but rather ugly. When you want to use the variables later,
you don't know what they're called! You'll have to compute their names and
do strange tricks once more.

Lists and dictionaries were invented for this sort of thing.

pdict = {}
while p != 0:
   pdict[p] = string.replace(component[control], ",", "")
   p = p-1
   control = control+1

print pdict

Or make it an empty list ([]), and append the strings to it.
