Python 实现99乘法表

首先，我们来回忆一下99乘法表长什么样子吧

进入正题：实现99乘法表

一、For循环

1 for i in range(1,10):
2     for j in range(1,i+1):
3         print("%d*%d=%d"%(i,j,i*j),end=" ")
4     print("")

二、While循环

1 n=1;sum=1
2 while n <= 9:
3     i = 1 
4     while i <= n:
5         sum = i*n
6         print(\'%d*%d=%d\'%(i,n,sum),end=\' \')
7         i = i+1
8     print(\'\')
9     n = n+1
