用Python打印九九乘法表下三角

Sure, here's the code to print the lower triangle of the multiplication table using Python:
```
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j}x{i}={i*j}", end="\t")
print()
```
This will output:
```
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
```

python打印九九乘法表倒
下三角和正三角的代码实现。
下三角:
```python
i = 9
while i >= 1:
j = 1
while(j <= i):
print('%d*%d=%-3d'%(i,j,i*j),end=' ')
j += 1
print('')
i -= 1
```
正三角:
```python
i = 1
while i <= 9:
j = 1
while(j <= i):
print('%d*%d=%-3d'%(i,j,i*j),end=' ')
j += 1
print('')
i += 1
```
