It is possible, using exec, but it is not the right solution to your
problem. You want a bunch of lists each associated with a name. The way
to do this is put the lists in a dict; the name is the key, the list is
the value. Your example would look like this:
lists = {}
for i in range(5):
lists['list_%i' % (i)] = []
