Using a loop in Python to name variables

Question

How do I use a loop to name variables? For example, if I wanted to have a variable double_1 = 2, double_2 = 4 all the way to double

Answer 1

Although I doubt you really need to do what you want, here's a way:

namespace = globals()
for x in range(1, 13):
    namespace['double_%d' % x] = x * 2

print double_1
print double_2
   ...
print double_12

globals() returns a dictionary representing the current global symbol table (the dictionary of the current module). As you can see, it's possible to add arbitrary entries to it.
