好的,以下是一个打印九九乘法表的示例代码:
```
for i in range(1, 10):
for j in range(1, i+1):
print("%d*%d=%d" % (i, j, i*j), end="\t")
print("")
```
输出结果:
```
1*1=1
2*1=2 2*2=4
3*1=3 3*2=6 3*3=9
4*1=4 4*2=8 4*3=12 4*4=16
5*1=5 5*2=10 5*3=15 5*4=20 5*5=25
6*1=6 6*2=12 6*3=18 6*4=24 6*5=30 6*6=36
7*1=7 7*2=14 7*3=21 7*4=28 7*5=35 7*6=42 7*7=49
8*1=8 8*2=16 8*3=24 8*4=32 8*5=40 8*6=48 8*7=56 8*8=64
9*1=9 9*2=18 9*3=27 9*4=36 9*5=45 9*6=54 9*7=63 9*8=72 9*9=81
```

好的,这是一个打印九九乘法表的 Python 程序:
```
for i in range(1, 10):
for j in range(1, i + 1):
print("%d * %d = %d" % (j, i, i * j), end="\t")
print("")
```
输出结果:
```
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

### 回答2:
可以使用嵌套循环来实现打印九九乘法表。
```python
for i in range(1, 10):
for j in range(1, i + 1):
result = i * j
print(f"{j} * {i} = {result}\t", end="")
print()
```
这段代码首先使用外层循环 `for i in range(1, 10)` 遍历每一行,然后内层循环 `for j in range(1, i + 1)` 遍历当前行需要打印的乘法表达式。`result = i * j` 计算乘法表达式的结果,然后通过 `print()` 函数打印出来。
使用 `\t` 进行制表符的输出,可以让每个乘法表达式垂直对齐。同时,使用 `end=""` 使得乘法表达式连续打印在同一行上。最后,通过 `print()` 函数打印换行符将每一行隔开,打印整个九九乘法表。
执行该程序,就可以打印出如下的九九乘法表:
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

当然,我可以帮您写一个能打印九九乘法表的Python程序。以下是一个简单的实现:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j} * {i} = {i*j}", end='\t')
print()
```
运行以上程序,将会输出以下九九乘法表:
```
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
```
希望这对您有帮助,如果还有其他问题,请随时问我。
用Python编写程序。打印九九乘法表
用Python编写程序打印九九乘法表可以嵌套循环来实现。以下是示例代码:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j} * {i} {i*j}", end="\t")
print()
`
这段代码使用了两个嵌套for循环,外层循环控制行数,内层循环控制每行的列数。在内层循环中,使用f-string格式化输出乘法表的每一项,并使用制表符`\t`分隔每一项。最后,使用`print()`函数换行。
