Rather than creating 1000000 variables, create a list with 1000000 values.
data = []
for i in range(1000000):
data.append(i*i) # or whatever data you want in your variables

This can be very nicely abbreviated with a list comprehension:
data = [ i*i for i in range(1000000) ]

In general, when you think you need to create a bunch of variables with 
repetive names, you should probably use a list or dictionary instead.
