Firstly I want to say thank you in advance for any and all help it's small for some but big for others and you have my gratitude! I have a list of numbers and need to analyze them in two different ways. [[ 0, 1, 0, 1, 0], [1, 1, 1, 1, 1], [ 0, 1, 1, 1, 0]] Firstly I need to add up any 1's and group them but ONLY if they're after each other. For this example: >>>[[1, 1], [5], [3]] (if 0 then post a 0) Then I need to add each row but one column at a time [[ **0**, 1, 0, 1, 0], [**1**, 1, 1, 1, 1], [ **0**, 1, 1, 1, 0]] >>>1 (Continues to the next column) [[ 0, **1**, 0, 1, 0], [1, **1**, 1, 1, 1], [ 0, **1**, 1, 1, 0]] >>>3 etc, etc. Thanks again!
