python插入排序算法实例分析

本文实例讲述了python插入排序算法。分享给大家供大家参考。具体如下：

def insertsort(array): 
  for removed_index in range(1, len(array)): 
    removed_value = array[removed_index] 
    insert_index = removed_index 
    while insert_index > 0 and array[insert_index - 1] > removed_value: 
      array[insert_index] = array[insert_index - 1] 
      insert_index -= 1 
    array[insert_index] = removed_value

另外一个版本：

def insertsort(array): 
  for lastsortedelement in range(len(array)-1): 
    checked = lastsortedelement 
    while array[checked] > array[lastsortedelement + 1] and checked >= 0: 
      checked -= 1 
    #Insert the number into the correct position 
    array[checked+1], array[checked+2 : lastsortedelement+2] = array[lastsortedelement+1], array[checked+1 : lastsortedelement+1] 
  return array

希望本文所述对大家的Python程序设计有所帮助。
