Multiplication table

Description:

Your task, is to create NxN multiplication table, of size provided in parameter.

for example, when given size is 3:

1 2 3
2 4 6
3 6 9

for given example, the return value should be: [[1,2,3],[2,4,6],[3,6,9]]

 

 

 

Solution:

1. Use the for statement twice to create a two-dimensional array.

2. The numbers in the given array are added in the second for statement.

3. Returns the numbers in a two-dimensional array.

 

 

def multiplication_table(size):
    result = []        
    for i in range(1, size+1):
        count, arr = 0, []
        for _ in range(size):
            count += i
            arr.append(count)
        result.append(arr)
    return result

 

 

 

Best Practice:

def multiplicationTable(size):
    return [[j*i for j in range(1, size+1)] for i in range(1, size+1)]
