以下是打印九九乘法表的 Python 代码:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j}x{i}={i*j}", end="\t")
print()
```
输出结果:
```
1x1=1
1x2=2 2x2=4
1x3=3 2x3=6 3x3=9
1x4=4 2x4=8 3x4=12 4x4=16
1x5=5 2x5=10 3x5=15 4x5=20 5x5=25
1x6=6 2x6=12 3x6=18 4x6=24 5x6=30 6x6=36
1x7=7 2x7=14 3x7=21 4x7=28 5x7=35 6x7=42 7x7=49
1x8=8 2x8=16 3x8=24 4x8=32 5x8=40 6x8=48 7x8=56 8x8=64
1x9=9 2x9=18 3x9=27 4x9=36 5x9=45 6x9=54 7x9=63 8x9=72 9x9=81
```

用python编写程序,打印九九乘法表。要求输出九九乘法表的下三角显示效果
你可以使用嵌套循环以及字符串格式化来打印出九九乘法表的下三角部分。以下是一个简单的Python程序示例:
```python
for i in range(1, 10): # 循环i从1到9
for j in range(i, 10): # 循环j从i到9
# 控制只打印i*j这一行的部分数字,形成下三角形
print(f'{i}x{j}={i*j}', end='\t') # end='\t'使得输出之间有空格
print() # 每行结束后换行
```
运行此程序,你会得到如下的九九乘法表下三角部分:
```
1x1=1
1x2=2 2x2=4
1x3=3 2x3=6 3x3=9
1x4=4 2x4=8 3x4=12 4x4=16
1x5=5 2x5=10 3x5=15 4x5=20 5x5=25
1x6=6 2x6=12 3x6=18 4x6=24 5x6=30 6x6=36
1x7=7 2x7=14 3x7=21 4x7=28 5x7=35 6x7=42 7x7=49
1x8=8 2x8=16 3x8=24 4x8=32 5x8=40 6x8=48 7x8=56 8x8=64
1x9=9 2x9=18 3x9=27 4x9=36 5x9=45 6x9=54 7x9=63 8x9=72 9x9=81
```
