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] 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] 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。
