本文所述的Python實現(xiàn)冒泡，插入，選擇排序簡單實例比較適合Python初學者從基礎開始學習數(shù)據(jù)結構和算法，示例簡單易懂，具體代碼如下：
# -*- 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的選擇排序 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 alistalist = [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)
