Python打印九九乘法表

1.for循环

print('输出一个九九乘法表：')
for i in range(1, 10):
    for j in range(1, i+1):
        print('{}*{}={}'.format(i, j, i * j), end='\t')
    print()

2.while嵌套循环

# 99乘法表
i = 1
while i <= 9:
    j = 1
    while j <= i:
        print(i, '*', j, '=', i * j, end='   ')
        j += 1
    print()
    i += 1
