Python 冒泡,选择,插入排序使用实例

本文主要是介绍Python 冒泡,选择,插入排序使用实例,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

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。
