Python中用双循环打印九九乘法表

在Python中,可以使用嵌套循环来打印九九乘法表。具体实现方法如下:
```python
for i in range(1, 10):
for j in range(1, i+1):
print("%d*%d=%d" % (j, i, i*j), end='\t')
print()
```
上述代码中,外层循环控制行数,内层循环控制列数,通过字符串格式化输出每个乘法表达式,其中`%d`表示整数占位符,`\t`表示制表符,`end='\t'`表示不换行输出。

```
for i in range(1, 10):
for j in range(1, i+1):
print('{}*{}={}'.format(j, i, i*j), end='\t')
print()
```
输出结果:
```
