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。
