In Python I have a series of nested for loops in this format:

for i in range(2):
    for j in range(2):
      for k in range(2):

and so on, all with the same range. Is there an easy way to simplify this into something like: for i, j, k in range(2)? I have been looking for a way to condense it down to one line and haven't found one.

  • This isn't necessarily a dupe as it can be solved in different ways based on what the intention is. If OP wants to select different 3-length combinations (with repeats) from a pool of 2 items, then they could iterate with "for i,j,k in itertools.combinations_with_replacement(range(2), 3)" – Jeremy Brown Sep 16 '14 at 17:50

    Aaaaand I just realized that I'm wrong and combinations_with_replacement didn't give what I expected. itertools.product(range(2), repeat=3) would be correct. – Jeremy Brown Sep 16 '14 at 19:11
