Python merge list

Merge two or more lists into one list list , The elements in each input list are combined according to the position of each input list .

• Used in conjunction with list derivation max() To get the length of the longest list in the parameter .
• range() Use with variables ,max_length The number of cycles is as many as the elements in the longest list .
• If the list is shorter than max_length, be fill_value For remaining items

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
