Split a list into list of lists based on modulus of index in Python
Question:
I’d like to write elements of lists to alternating files, and figured I would process the list before.
With a list of strings where the order is important, like ordered_favorite_colors =["red", "blue", "green", "hazel"], and variable number of files number_of_files, I’d like to partition the list into multiple lists so that each file can contain my most favorite color remaining. If number_of_files = 1, the result would be [["red", "blue", "green", "hazel"]], if number_of_files = 3 the result would be [["red", "hazel"], ["blue"], ["green"]]
Answers:
l = [0, 1, 2, 3, 4, 5, 6]
size = 3
res = [l[i::size] for i in range(size)]
