python九九乘法表的打印输出
时间: 2023-11-04 21:58:23 浏览: 80
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
```

### 回答1:
可以使用嵌套的for循环来打印九九乘法表,以下是示例代码:
```python
for i in range(1, 10):
for j in range(1, i+1):
print('{} x {} = {}'.format(j, i, i*j), end='\t')
print()
```
输出结果为:
```
1 x 1 = 1
1 x 2 = 2 2 x 2 = 4
1 x 3 = 3 2 x 3 = 6 3 x 3 = 9
1 x 4 = 4 2 x 4 = 8 3 x 4 = 12 4 x 4 = 16
1 x 5 = 5 2 x 5 = 10 3 x 5 = 15 4 x 5 = 20 5 x 5 = 25
1 x 6 = 6 2 x 6 = 12 3 x 6 = 18 4 x 6 = 24 5 x 6 = 30 6 x 6 = 36
1 x 7 = 7 2 x 7 = 14 3 x 7 = 21 4 x 7 = 28 5 x 7 = 35 6 x 7 = 42 7 x 7 = 49
1 x 8 = 8 2 x 8 = 16 3 x 8 = 24 4 x 8 = 32 5 x 8 = 40 6 x 8 = 48 7 x 8 = 56 8 x 8 = 64
1 x 9 = 9 2 x 9 = 18 3 x 9 = 27 4 x 9 = 36 5 x 9 = 45 6 x 9 = 54 7 x 9 = 63 8 x 9 = 72 9 x 9 = 81
```

Python九九乘法表是一种打印9行9列的乘法表格的编程练习题。我们可以使用嵌套循环来实现这个乘法表。
```python
for i in range(1, 10): # 用于控制行数
for j in range(1, i+1): # 用于控制每行的列数,从1到i
print(f'{j} * {i} = {j*i}', end='\t') # 打印乘法表达式,使用制表符('\t')分隔
print() # 打印完一行后换行
```
这段代码中,外层的循环`for i in range(1, 10)`用于控制行数,内层的循环`for j in range(1, i+1)`用于控制每行的列数。`print(f'{j} * {i} = {j*i}', end='\t')`打印出每个乘法表达式,并使用制表符('\t')分隔每个表达式的结果。最后一行的`print()`语句用于换行。
运行以上代码,就可以输出如下九九乘法表:
```
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
```
通过这个例子,我们能够熟悉掌握了Python语言的基础语法和控制流程语句的使用。
### 回答3:
python九九乘法表可以通过嵌套循环来实现。下面是一个例子:
```python
for i in range(1, 10):
for j in range(1, i+1):
print(j, "*", i, "=", i * j, end="\t")
print()
```
首先,外层的`for`循环用来控制打印乘法表的行数,循环变量`i`的取值范围是1到9。
内层的`for`循环用来控制打印每一行的乘法式子,循环变量`j`的取值范围是1到`i`。对于每个`j`,打印`j * i = j*i`的格式,并使用`\t`制表符分隔每个乘法式子。
最后,每打印完一行乘法式子后,使用`print()`进行换行。
运行上述代码,就可以在控制台上打印出python的九九乘法表,结果如下所示:
```
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
```
以上就是用python打印九九乘法表的方法。
