【python习题】九九乘法表

九九乘法表实现

• 法一（for循环）

sum = 0
for i in range(1,10):
    for j in range(1,i+1,):
        sum = i*j
        print("%d * %d = %d"%(i,j,sum),end = '\t')
    print(' ')

• 法二（while循环）

i = 1
sum = 0
while i < 10:
    j = 1
    while j < i+1:
        sum = i * j
        print("%d * %d = %d" % (i, j, sum), end='\t')
        j += 1
    i += 1
    print(' ')
