精彩书摘

　　《Python入门（影印版 英文版）》：
　　That initial blank output line is the empty string''， which stands for the current directory.If '' is First in sys .path， Python looks in the current directory first when you try to import something： import report looks for report.py.
　　The first match willbe used.This means that ifyou define a module named random and it's in the search path before the standard library， you won't be able to access the standard library's random now.
　　Packages
　　We went from single lines of code， to multiline functions， to standalone programs， to multiple modulesin the same directory To allow Python applications to scale even more， you can organize modules into file hierarchies called packages.
　　Maybe we want different types of text forecasts： one for the next day and one for the next week.One way to structure this is to make a directory named sources， and create two modules within it： daily.py and weekly.py.Each has a function called forecast.The daily version returns a string， and the weekly version returns a list of seven strings.Here's the main program and the two modules.（The enuvierate（） function takes apart alist and feeds each item of the list to the for loop， adding a number to each item as a liffle bonus.）.

订单号59491621309包装人员极不负责任，把箱子装不下的燕窝硬挤进去，导致礼品变形严重。送人的搞成这样还得换货真的很麻烦。

知道你们过购物节忙，快递小哥也辛苦，一般都不忍心不给5分。但是书的包装和运输能不能用点心？回来好几本书角折了，折一下不要紧，可一本书能有一半纸的每一页都有折的痕迹，看着真膈应！
