in python, how do i iterate a nested dict with a dynamic number of nests?
aDict[1]=[1,2,3]
aDict[2]=[7,8,9,10]
aDict[n]=[x,y]

for l1 in aDict[1]:
  for l2 in aDict[2]:
    for ln in aDict[n]:
      # do stuff with l1, l2, ln combination.

from itertools import product

for vals in product(*list(aDict.values())):
    # vals will be (l1, l2, ..., ln) tuple

from itertools import product

for vals in product( *[aDict[i] for i in sorted(aDict.keys())]):
    print vals
