Iterating through a multidimensional array in Python

Question

I have created a multidimensional array in Python like this:

self.cells = np.empty((r,c),dtype=np.object)

Now I want to iterate through all

Answer 1

No one has an answer that will work form arbitrarily many dimensions without numpy, so I'll put here a recursive solution that I've used

def iterThrough(lists):
  if not hasattr(lists[0], '__iter__'):
    for val in lists:
      yield val
  else:
    for l in lists:
      for val in iterThrough(l):
        yield val

for val in iterThrough(
  [[[111,112,113],[121,122,123],[131,132,133]],
   [[211,212,213],[221,222,223],[231,232,233]],
   [[311,312,313],[321,322,323],[331,332,333]]]):
  print(val)
  # 111
  # 112
  # 113
  # 121
  # ..

This doesn't have very good error checking but it works for me
