【Kata Daily 190911】Multiplication Tables（乘法表）

题目：

Create a function that accepts dimensions, of Rows x Columns, as parameters in order to create a multiplication table sized according to the given dimensions. **The return value of the function must be an array, and the numbers must be Fixnums, NOT strings.

Example:

multiplication_table(3,3)

1 2 3
2 4 6
3 6 9

-->[[1,2,3],[2,4,6],[3,6,9]]

Each value on the table should be equal to the value of multiplying the number in its first row times the number in its first column.

 

解题办法：

def multiplication_table(row, col):
    L = []
    # Good Luck!
    for i in range(1, row+1):
        L1 = []
        for j in range(1, col+1):
           mul = i * j
           L1.append(mul)
        L.append(L1)
    return L

这题还是挺简单的。按照思路来就好

 

看一下网友的简写一句话的写法：

def multiplication_table(row,col):
    return [[(i+1)*(j+1) for j in range(col)] for i in range(row)]
