这是一些从我的github repo 拿回来的很早的笔记 python 的脚本式运行 % run d : / 1. py 这是脚本式运行Python! 练习题 1、 求从1到100的数字中所有能既能被3整除，又能被5整除的数字有哪些。 LsNum = [ ] for i in range ( 1 , 101 ) : if i % 3 == 0 and i % 5 == 0 : LsNum . append ( i ) print ( LsNum ) [15, 30, 45, 60, 75, 90] 2、 输入一个字符串返回满足以下条件的字符串 如果字符串长度大等于3，添加 ‘ing’ 到字符串的末尾 如果字符串是以 ‘ing’ 结尾的，就在末尾添加 ‘ly’ 如果字符串长度小于3，返回原字符串 StrInput = input ( "请输入字符串：" ) StrLength = len ( StrInput ) if StrLength < 3 : NewStr = StrInput if StrLength >= 3 : if StrInput . endswith ( "ing" ) : NewStr = StrInput + "ly" else : NewStr = StrInput + "ing" print ( NewStr ) 请输入字符串：aaing aaingly

Description： Polycarp analyzes the prices of the new berPhone. At his disposal are the prices for n last days: a1,a2,…,an, where ai is the price of berPhone on the day i. Polycarp considers the price on the day i to be bad if later (that is, a day with a greater number) berPhone was sold at a lower price. For example, if n=6 and a=[3,9,4,6,7,5], then the number of days with a bad price is 3 — these are days 2 (a2=9), 4 (a4=6) and 5 (a5=7). Print the number of days with a bad price. You have to answer t independent data sets. Input： The first line contains an integer t (1≤t≤10000) — the number

/bin/sh^M: bad interpreter:没有那个文件或目录解决 执行脚本时发现如下错误： /bin/sh^M: bad interpreter: 没有那个文件或目录 错误分析: 因为操作系统是windows，我在windows下编辑的脚本，所以有可能有不可见字符。 脚本文件是DOS格式的, 即每一行的行尾以\n\r来标识, 其ASCII码分别是0x0D, 0x0A. 可以有很多种办法看这个文件是DOS格式的还是UNIX格式的, 还是MAC格式的 解决方法： vim filename 然后用命令 :set ff? #可以看到dos或unix的字样. 如果的确是dos格式的。 然后用 :set ff=unix #把它强制为unix格式的, 然后存盘退出。 再次运行脚本。 另外一种解决方法是使用dos2unix命令转一下，即输入： dos2unix 文件名 来源： oschina 链接： https://my.oschina.net/u/160700/blog/206162

php程序出现 502 bad gateway 的分析流程 标签（空格分隔）： php 502 http 最近在开发一个基于php的充值后台, 一个很简单的充值回调接口尽然有时候会出现502的错误. 奇怪的是在本地都测试相当正常, 部署到服务器之后就会出现502错误. 分析步骤: 1. 怀疑配置环境出错 由于本地的环境是Windows+Apache+php, 服务器是centos+nginx+php-fpm, 首先想到的是服务器环境配置出错. 百度上搜索 php 502 出现一大堆关于php与nginx配置错误导致的文章,比如: http://www.nginx.cn/102.html http://www.cnblogs.com/jackluo/p/3366612.html 于是, 各种php, nginx, php-fpm, linux 各种配置文件一个一个改, 一次一次重试. 然而这并没有什么用... 2. 观察 php, nginx 日志 观察 php, nginx 日志, 这一步应该是出现问题首先应该做的事, 这也是坑踩多了学到的经验. nginx的日志: /usr/local/nginx/logs/error.log php-fpm的日志: /usr/local/php5.6/var/log/php-fpm.log 不同的环境可能位置稍有区别 从日志中发现了更劲爆的错误
