[FIXED] multiplying each element in a list in a way that- each element multiply with next and stores the value in a table

Issue

N	l1	l2	l3	l4	l5
l1	1	2	3	4	5
l2	2	4	6	8	10
l3	3	6	9	12	15
l4	4	8	12	16	20
l5	5	10	15	20	25

this needs to be the output of input list:(input list: l=[1,2,3,4,5]) I want to also publish the output grid in a csv.

Solution

You can use a nested list comprehension.

import csv

l = [1,2,3,4,5]
table = [[a*b for b in l] for a in l]
with open("output.csv", "w", newline="") as f:
    writer = csv.writer(f)
    writer.writerows(table)
