《笨办法学Python》 第39课手记

本节课讲列表的操作，用来做练习的代码中出现了之前用到过的几个函数，是一节复习课。你需要记住它们。

原代码如下：

ten_things = "Apples Orange Crows Telephone Light Sugar"print "Wait there's not 10 things in that list, let's fix that."stuff = ten_things.split(' ')more_stuff = ["Day", "Night", "Song", "Frisbee", "Corn", "Banana", "Girl", "Boy"]while len(stuff) != 10:    next_one = more_stuff.pop()    print "Adding: ", next_one    stuff.append(next_one)    print "There's %d items now." % len(stuff)print "There we go: ", stuffprint "Let's do some things with stuff"print stuff[1]print stuff[-1] # whoa!! fancyprint stuff.pop()print ' '.join(stuff) # what? cool!print '#'.join(stuff[3:5]) # super stellar!

结果如下：

本节课涉及的知识：

1.stuff.split(’ ‘)，以空格为标志分割字符串，默认全部分割，可以在括号里”后面指定参数以使解释器按规定次数分割。
