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 a 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() and itertools.zip_longest() provide similar functionality to this snippet.
Code:
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
