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。
