python代码实现九九乘法口诀表

在Python中,可以使用简单的循环结构来打印出九九乘法口诀表。这是一个常见的编程练习,下面是一个简单的例子:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f'{j} * {i} = {i*j}', end='\t')
print() # 每行结束后换行
```
这个程序会通过两个嵌套循环遍历乘数1到9,并计算每个乘积。`end='\t'`表示输出时不换行,而是保留制表符分隔。每次外层循环结束后,通过`print()`函数添加一个空行。
运行上述代码,你会得到如下的九九乘法口诀表:
```
1 * 1 = 1
1 * 2 = 2 2 * 2 = 4
1 * 3 = 3 2 * 3 = 6 3 * 3 = 9
1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16
1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25
1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36
1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49
1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64
1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81
