Iteration over list slices

Question

I want an algorithm to iterate over list slices. Slices size is set outside the function and can differ.

In my mind it is something like:

for list_of_x         


        

Answer 1

Do you mean something like:

def callonslices(size, fatherList, foo):
  for i in xrange(0, len(fatherList), size):
    foo(fatherList[i:i+size])

If this is roughly the functionality you want you might, if you desire, dress it up a bit in a generator:

def sliceup(size, fatherList):
  for i in xrange(0, len(fatherList), size):
    yield fatherList[i:i+size]

and then:

def callonslices(size, fatherList, foo):
  for sli in sliceup(size, fatherList):
    foo(sli)
