最近学习了python基础，写一下3大排序练练手：

复制代码 代码如下:

//冒泡排序

def bubble_sort(seq):

for i in range(len(seq)):

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

if seq[j] < seq[i]:

tmp = seq[j]

seq[j] = seq[i]

seq[i] = tmp

//选择排序

def selection_sort(seq):

for i in range(len(seq)):

position = i

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

if seq[position] > seq[j]:

position = j

if position != i:

tmp = seq[position]

seq[position] = seq[i]

seq[i] = tmp

//插入排序

def insertion_sort(seq):

if len(seq) > 1:

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

while i > 0 and seq[i] < seq[i-1]:

tmp = seq[i]

seq[i] = seq[i-1]

seq[i-1] = tmp

i = i - 1

//

if __name__ == "__main__":

print "--------bubble_sort-------------"

seq = [22,1,33,4,7,6,8,9,11]

bubble_sort(seq)

print seq

print "--------selection_sort-------------"

seq = [88,44,33,4,7,6,8,9,11]

selection_sort(seq)

print seq

print "--------insertion_sort-------------"

seq = [777,44,33,4,7,6,1111,100,11]

insertion_sort(seq)

print seq

以上就是3则Python中冒泡，选择，插入排序的代码及使用方法了，希望小伙伴们能够喜欢。
