1、插入排序

def insert_sort(lists):

# 插入排序

count = len(lists)

for i in range(1, count):

key = lists[i]

j = i - 1

while j >= 0:

if lists[j] > key:

lists[j + 1] = lists[j]

lists[j] = key

j -= 1

return lists

2、希尔排序

def shell_sort(lists):

# 希尔排序

count = len(lists)

step = 2

group = count / step

while group > 0:

for i in range(0, group):

j = i + group

while j < count:

k = j - group

key = lists[j]

while k >= 0:

if lists[k] > key:

lists[k + group] = lists[k]

lists[k] = key

k -= group

j += group

group /= step

return lists

3、冒泡排序

def bubble_sort(lists):

# 冒泡排序

count = len(lists)

for i in range(0, count):

for j in range(i + 1, count):

if lists[i] > lists[j]:

lists[i], lists[j] = lists[j], lists[i]

return lists

4、快速排序

def quick_sort(lists, left, right):

# 快速排序

if left >= right:

return lists

key = lists[left]

low = left

high = right

while left < right:

while left < right and lists[right] >= key:

right -= 1

lists[left] = lists[right]

while left < right and lists[left] <= key:

left += 1

lists[right] = lists[left]

lists[right] = key

quick_sort(lists, low, left - 1)

quick_sort(lists, left + 1, high)

return lists

5、直接选择排序

def select_sort(lists):

# 选择排序

count = len(lists)

for i in range(0, count):

min = i

for j in range(i + 1, count):

if lists[min] > lists[j]:

min = j

lists[min], lists[i] = lists[i], lists[min]

return lists

6、堆排序

# 调整堆

def adjust_heap(lists, i, size):

lchild = 2 * i + 1

rchild = 2 * i + 2

max = i

if i < size / 2:

if lchild < size and lists[lchild] > lists[max]:

max = lchild

if rchild < size and lists[rchild] > lists[max]:

max = rchild

if max != i:

lists[max], lists[i] = lists[i], lists[max]

adjust_heap(lists, max, size)

# 创建堆

def build_heap(lists, size):

for i in range(0, (size/2))[::-1]:

adjust_heap(lists, i, size)

# 堆排序

def heap_sort(lists):

size = len(lists)

build_heap(lists, size)

for i in range(0, size)[::-1]:

lists[0], lists[i] = lists[i], lists[0]

adjust_heap(lists, 0, i)

7、归并排序

def merge(left, right):

i, j = 0, 0

result = []

while i < len(left) and j < len(right):

if left[i] <= right[j]:

result.append(left[i])

i += 1

else:

result.append(right[j])

j += 1

result += left[i:]

result += right[j:]

return result

def merge_sort(lists):

# 归并排序

if len(lists) <= 1:

return lists

num = len(lists) / 2

left = merge_sort(lists[:num])

right = merge_sort(lists[num:])

return merge(left, right)

8、基数排序

import math

def radix_sort(lists, radix=10):

k = int(math.ceil(math.log(max(lists), radix)))

bucket = [[] for i in range(radix)]

for i in range(1, k+1):

for j in lists:

bucket[j/(radix**(i-1)) % (radix**i)].append(j)

del lists[:]

for z in bucket:

lists += z

del z[:]

return lists
