Is there any special reason you can't use a list or a dictionary?

p = []
max = input("How many lists? ")
for i in range(max):
    p.append([x,y,z])
# note that this will create lists from
# p[0] to p[max-1], inclusive.

p = {}
max = input("How many lists? ")
for i in range(max):
    p["P" + str(i+1)] = [x,y,z]
# this will create lists from
# p["P1"] to p["Pmax"], inclusive.
