这几种算法包括了：冒泡排序，插入排序，选择排序，快速排序和希尔排序,Python版本：2.7.3，具体代码如下：

import sys, getopt, random

def bubble_sort(seq):

for i in range(len(seq)):

for j in range(1,len(seq)):

if seq[j-1]>seq[j]:

seq[j-1], seq[j]= seq[j], seq[j-1]

return seq

def insertion_sort(seq):

for i in range(1,len(seq)):

tmp=seq[i]

pos=i;

for j in range(i-1,-1,-1):

if seq[j]>tmp:

seq[j+1]=seq[j]

pos=j

seq[pos]=tmp

return seq

def selection_sort(seq):

for i in range(len(seq)):

min_index=i;

for j in range(i,len(seq)):

if seq[j]<seq[min_index]:

min_index=j

seq[i],seq[min_index]=seq[min_index],seq[i]

return seq

def partition(seq,p,l,r):

pivot = seq[p]

seq[p],seq[r]=seq[r],seq[p]

p_pos = l

for i in range(l,r):

if seq[i]<=pivot:

seq[i],seq[p_pos]=seq[p_pos],seq[i]

p_pos=p_pos+1

seq[p_pos],seq[r]=seq[r],seq[p_pos]

return p_pos

def quick_sort(seq,left,right):

if left < right:

pivot = random.randint(left,right)

mid = partition(seq,pivot,left,right)

quick_sort(seq,left,mid-1)

quick_sort(seq,mid+1,right)

return seq

def shell_sort(seq):

incr = len(seq)/2

while(incr>=1):

for i in range(incr,len(seq)):

tmp=seq[i]

pos=i;

for j in range(i-incr,-1,-incr):

if seq[j]>tmp:

seq[j+incr]=seq[j]

pos=j

seq[pos]=tmp

incr = incr/2

return seq

def usage():

print 'Usage: python sort.py sorttype[-q|-i|-b|-s|--shell] sequence'

print 'Example: python sort.py -q 11,32,3,24,5'

def main():
