python九九乘法表的打印输出
时间: 2023-11-04 15:58:23 浏览: 85
九九乘法表的打印输出可以通过使用while循环的嵌套来实现。下面是一个Python代码示例:
```
j = 1
while j <= 9:
i = 1
while i <= j:
print(f'{i} * {j} = {i*j}', end='\t')
i += 1
print()
j += 1
```
该代码使用了两个嵌套的while循环,外部循环控制行数,内部循环控制每行的乘法表达式输出。每次内部循环打印一个乘法表达式,使用`end='\t'`来保持每个表达式之间的水平间距。在内部循环结束后,使用`print()`来换行。外部循环每进行一次,行数就增加1,直到达到9为止。

在Python中,我们可以使用嵌套循环和字符串格式化来创建一个整洁的九九乘法表。以下是一个简单的例子:
```python
for i in range(1, 10):
# 外层循环控制行数
for j in range(1, i + 1):
# 内层循环控制列数,使用'\t'实现对齐
print(f'{j} * {i} = {i*j}\t', end='')
# 每行结束后换行
print()
```
运行这段代码后,你会在控制台看到九九乘法表,每一行的乘法表达式都对齐排列,例如:
```
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
```
python九九乘法表
以下是使用Python打印九九乘法表的代码:
```python
for i in range(1, 10):
for j in range(1, 10):
print(i, "*", j, "=", i*j, end="\t")
if j == i:
print()
break
```
输出结果为:
```
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
