There are ways to do this, but what you likely actually want is just  
to put several arrays in a python list and then index into the list,  
instead of constructing numbered names.

e.g.:

array_list = []

for whatever:
   array_list.append(numpy.array(whatever))

for array in array_list:
   do_something(array)

given_array = array_list[i]
