本文实例讲述了python冒泡排序简单实现方法。分享给大家供大家参考。具体实现方法如下:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

#!/usr/bin/python
import random
def bubble_sort(data):
length = len (data)
for i in range ( len (data) - 1 ):
for j in range ( len (data) - 1 ):
if (data[j] < data[j + 1 ]):
tmp = data[j]
data[j] = data[j + 1 ]
data[j + 1 ] = tmp
r = random.Random()
data = []
for n in range ( 0 , 20 ):
data.append(r.randint( 1 , 300 ))
print data, len (data)
bubble_sort(data)
print data

运行结果如下:
[115, 14, 246, 125, 94, 78, 275, 163, 64, 72, 245, 1, 97, 53, 86, 270, 137, 69, 74, 182] 20
[275, 270, 246, 245, 182, 163, 137, 125, 115, 97, 94, 86, 78, 74, 72, 69, 64, 53, 14, 1]
希望本文所述对大家的Python程序设计有所帮助。
