1. 选择排序

def selectSort(l):
for i in range(len(l)):
j = i + 1
t_min = l[i]
loc_min = i
for j in range(j,len(l)):

t_min = l[j]
loc_min = j
if loc_min != i:

l[loc_min] = t
2. 冒泡排序

def bubbleSort(l):
for i in range(len(l)-1,1,-1):
for j in range(i):
if l[j] > l[j+1]:
t = l[j+1]
l[j+1] = l[j]
l[j] = t
3. 插入排序
--
--
def insertSort(param):
p_len = len(param)
for i in range(1,p_len):
key = param[i]
#for j in range(1,i+1)[::-1]:
for j in range(i,0,-1):
#if j>0 and key < param[j-1]:
if key < param[j-1]:
param[j] = param[j-1]
param[j-1] = key
4. 桶排序

--
def bucketSort(l):
min_,max_ = min_max(l)
bucket_len = max_ - min_ + 1
bucketList = [0] * bucket_len
rList = []
for e in l:
bucketList[e-min_] += 1 for i in range(bucket_len):
if bucketList[i] != 0:
for j in range(bucketList[i]):
rList.append(i + min_)
return rList def min_max(l):
min_ = max_ = l[0] for e in l:
if min_ > e:
min_ = e
if max_ < e:
max_ = e
return min_,max_
