用Python写一个九九乘法表
时间: 2024-03-06 11:22:45 浏览: 26
以下是python实现冒泡排序的代码:
```python
def bubble_sort(arr):
n = len(arr)
for i in range(n):
for j in range(n-i-1):
if arr[j] > arr[j+1]:
arr[j], arr[j+1] = arr[j+1], arr[j]
return arr
```
其中,`arr`是要排序的数组,`n`是数组的长度。在每一轮循环中,都比较相邻的两个元素,如果前一个元素比后一个元素大,则交换它们的位置。每一轮循环结束后,最后一个元素就是已排序好的元素中最大的一个,因此下一轮循环可以少比较一个元素。最终,当所有的轮次都完成时,数组就已经完成了排序。

使用python写一个九九乘法表
好的,下面是使用Python写的九九乘法表代码:
```python
for i in range(1, 10):
for j in range(1, i+1):
print("{}x{}={}\t".format(j, i, i*j), end="")
print()
```
输出结果如下:
```
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

好的,下面是Python代码实现九九乘法表:
```python
for i in range(1, 10):
for j in range(1, i+1):
print("{0} x {1} = {2}\t".format(i, j, i*j), end='')
print()
