Why do you assign those to variables?

Are you looking for something like this?

# UNTESTED (Poor styling of variable names is noted)
def recursiveMultiply(l, r, product): # list, range (no shadowing)
if r <= 0:
return sum
product *= l[r]
recursiveMultiply(l, r - 1, product) # r must be decremented
subsetrange = 15
multiplysubset, elemlist = [], list(range(15)) # Works with Py2 and Py3
assert subset_range <= len(elemlist)
for i in range(subsetrange):
multiplysubset.append(recursiveMultiply(elemlist, i, 0))
