select sort | Pyclear

http://pyclear.me/2016/08/27/2016-08-27-select-sort

When in doubt, use brute force. Def select sort(ary): for i in range(len(ary) : tmp = ary[i] index = ary.index(min(ary[i:]) ary[i] = ary[index] ary[index] = tmp return ary. Test = [23, 455, 234, 23423, 23, 4, 5, 6, 7, 3]. Result = [3, 4, 5, 6, 7, 234, 23423, 455, 23, 23]. Index = ary.index(min(ary[i:]). 改成index = i ary[i:].index(min(ary[i:]). Def select sort(ary): for i in range(len(ary) : tmp = ary[i] index = i ary[i:].index(min(ary[i:]) ary[i] = ary[index] ary[index] = tmp return ary.

When in doubt, use brute force. 里面有句话是精髓所在: The encoding is a crucial part of this translation proce. BIF(built-in functions) 和 type内置函数和一些类型对与解释器来说总是可用的, py2中存在于 builtin 模块中,py3的builtins模块中. BIF一些常见的没什么好说的,比较有意思的和有特色的记录了下用法 bytearray([x[). 除法div 10 ， 2 => 5 10 / 2 => 5.0 求余rem 10， 3 => 1 匿名函数sum = fn x, y -> x y end sum 10, 9 => 19 匿名函数是闭包，当前作用域(scope)内的其它变量都可. Select sort闲着没事，就想起写写排序的算法，因为从来没用Python写过算法，依据算法的原理很快就撸了个选择排序 def select sort(ary): for i in range(len(ary) : tmp = ary[i]. And Theme by Jacman.

collections | Pyclear

http://pyclear.me/2016/11/29/collections-module

When in doubt, use brute force. Collections提供了些新类型 deque和defaultdict, namedtuple等。 From collections import deque. Dq = deque([1,2],12). For i in range(3,15):. 用id来看添加值前后的内存地址会发现现的一个有意思的地方, 如果限制了大小，当满了以后那么添加新项目的话，会在相反的一端删除对象，添加了一个值后dq[0]的id变成了原来dq[1]的id值, 原来dq[0]里面的内容也被删除了, 这样的实现无疑保证了性能。 还有个基于双端数据结构的函数 rotate, 它可以轻易的旋转所有项，rotate的参数. From collections import namedtuple. NetAddress = nametuple('NetAddress', ['hostname','port']). A = NetAddress('localhost',80). Ahostname # 'localhost'. And Theme by Jacman.
