本文所述的Python实现冒泡，插入，选择排序简单实例比较适合Python初学者从基础开始学习数据结构和算法，示例简单易懂，具体代码如下：
# -*- coding: cp936 -*- #python插入排序 def insertSort(a): for i in range(len(a)-1): #print a,i for j in range(i+1,len(a)): if a[i]>a[j]: temp = a[i] a[i] = a[j] a[j] = temp return a #Python的冒泡排序 def bubbleSort(alist): for passnum in range(len(alist)-1,0,-1): #print alist,passnum for i in range(passnum): if alist[i]>alist[i+1]: temp = alist[i] alist[i] = alist[i+1] alist[i+1] = temp return alist #Python的选择排序 def selectionSort(alist): for i in range(len(alist)-1,0,-1): maxone = 0 for j in range(1,i+1): if alist[j]>alist[maxone]: maxone = j temp = alist[i] alist[i] = alist[maxone] alist[maxone] = temp return alist alist = [54,26,93,17,77,31,44,55,20] #print bubbleSort(alist) alist = [54,26,93,17,77,31,44,55,20] print selectionSort(alist)
