4.编写程序,使用for循环的嵌套结构打印9-9乘法表
时间: 2024-02-20 18:56:56 浏览: 33
以下是 Python 代码实现:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j}x{i}={i*j}\t", end="")
print()
```
使用外层 `for` 循环遍历 1 到 9 的所有数,内层 `for` 循环遍历 1 到当前外层循环变量的数。在内层循环中,使用 `print()` 函数输出乘法表的一行。使用了 `end` 参数将输出的内容以制表符结束,使得输出的乘法表更加整齐。最后,使用 `print()` 函数输出一个空行,换行下一行的乘法表。

编写程序,使用for循环的嵌套结构打印9-9乘法表
好的,下面是使用for循环嵌套打印9-9乘法表的Python代码:
```
for i in range(1, 10):
for j in range(1, 10):
print(i, "*", j, "=", i*j, end="\t")
if j == 9:
print("\n")
```
运行结果如下:
```
1 * 1 = 1 1 * 2 = 2 1 * 3 = 3 1 * 4 = 4 1 * 5 = 5 1 * 6 = 6 1 * 7 = 7 1 * 8 = 8 1 * 9 = 9
2 * 1 = 2 2 * 2 = 4 2 * 3 = 6 2 * 4 = 8 2 * 5 = 10 2 * 6 = 12 2 * 7 = 14 2 * 8 = 16 2 * 9 = 18
3 * 1 = 3 3 * 2 = 6 3 * 3 = 9 3 * 4 = 12 3 * 5 = 15 3 * 6 = 18 3 * 7 = 21 3 * 8 = 24 3 * 9 = 27
4 * 1 = 4 4 * 2 = 8 4 * 3 = 12 4 * 4 = 16 4 * 5 = 20 4 * 6 = 24 4 * 7 = 28 4 * 8 = 32 4 * 9 = 36
5 * 1 = 5 5 * 2 = 10 5 * 3 = 15 5 * 4 = 20 5 * 5 = 25 5 * 6 = 30 5 * 7 = 35 5 * 8 = 40 5 * 9 = 45
6 * 1 = 6 6 * 2 = 12 6 * 3 = 18 6 * 4 = 24 6 * 5 = 30 6 * 6 = 36 6 * 7 = 42 6 * 8 = 48 6 * 9 = 54
7 * 1 = 7 7 * 2 = 14 7 * 3 = 21 7 * 4 = 28 7 * 5 = 35 7 * 6 = 42 7 * 7 = 49 7 * 8 = 56 7 * 9 = 63
8 * 1 = 8 8 * 2 = 16 8 * 3 = 24 8 * 4 = 32 8 * 5 = 40 8 * 6 = 48 8 * 7 = 56 8 * 8 = 64 8 * 9 = 72
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
```
(for循环的嵌套)编写程序实现:打印九九乘法表。
好的,以下是Python语言实现九九乘法表的代码:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(f"{j}x{i}={i*j}", end="\t")
print()
```
输出结果为:
```
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
```
