Python 练习:九九乘法表

num = 1
while num <= 9:
    tmp = 1
    while tmp <= num:
        print(tmp, "*", num, "=", tmp*num, end="	")
        tmp += 1
    print("")
    num += 1

测试结果：

for i in range(1, 10):
    for j in range(1, i+1):
        print(str(j) + ' x ' + str(i) + ' = ' + str(i * j) + '	', end=' ')
    print('')

for i in range(1, 10):
    line = ''
    for j in range(1, i+1):
        line += '{0}*{1}={2:<2} '.format(j,i,i*j)
    print(line)

#{2:<2} 对应 i*j, :2 冒号是分割符合，< 表示左对齐，2表示宽度
