- class nestedloop(inputs, loop_order)[source]#
Zip list of lists in order
This function takes in a list of lists to iterate over, and their nesting order. It then yields tuples of items in the given order. Only tested for two levels but in theory supports an arbitrary number of items.
Generator yielding tuples of items, one for each list
>>> list(sc.nestedloop([['a','b'],[1,2]],[0,1])) [['a', 1], ['a', 2], ['b', 1], ['b', 2]]
Notice how the first two items have the same value for the first list while the items from the second list vary. If the loop_order is reversed, then:
>>> list(sc.nestedloop([['a','b'],[1,2]],[1,0])) [['a', 1], ['b', 1], ['a', 2], ['b', 2]]
Notice now how now the first two items have different values from the first list but the same items from the second list.
