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:

#!/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

Copy after login

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。
