Multiply by length

Problem to multiply the each and every digits with length of the given input.

Example-1:

Input    : n = [ 1, 3, 5, 4]
Output   : [4, 12, 20, 16]  

Example-2:

Input    : n = [ 1, 2, 3]
Output   : [3, 6, 9]

Solution

n = [ 1, 3, 5, 4]

a = len(n)

l = []

for x in n:

    l.append(x*a)

print(l)

Output

[4, 12, 20, 16]
