精彩書摘

　　《Python入門（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.）.
