+
+Merges two or more lists into a list of lists, combining elements from each of the input lists based on their positions.
+
+Use `max` combined with list comprehension to get the length of the longest list in the arguments. 
+Use `range()` in combination with the `max_length` variable to loop as many times as there are elements in the longest list.
+If a list is shorter than `max_length`, use `fill_value` for the remaining items (defaults to `None`).
+
+[`zip()`](https://docs.python.org/3/library/functions.html#zip) and [`itertools.zip_longest()`](https://docs.python.org/3/library/itertools.html#itertools.zip_longest) provide similar functionality to this snippet.

+```py
+def merge(*args, fill_value=None):
+  max_length = max([len(lst) for lst in args])
+  result = []
+  for i in range(max_length):
+    result.append([
+      args[k][i] if i < len(args[k]) else fill_value for k in range(len(args))
+    ])
+  return result
+```
+
+```py
+merge(['a', 'b'], [1, 2], [True, False]) # [['a', 1, True], ['b', 2, False]]
+merge(['a'], [1, 2], [True, False]) # [['a', 1, True], [None, 2, False]]
+merge(['a'], [1, 2], [True, False], fill_value = '_') # [['a', 1, True], ['_', 2, False]]

-Creates a list of elements, grouped based on the position in the original lists.
-
-Use `max` combined with `list comprehension` to get the length of the longest list in the arguments. 
-Loop for `max_length` times grouping elements. 
-If lengths of `lists` vary, use `fill_value` (defaults to `None`).
