Ex9 Printing, Printing, Printing

读书心法

进入到 Ex9 ，Zed 挑明说了这本书的组织模式: 用多个练习教授新东西。给你一段代码，自己输入，不懂的地方记下来。后续练习继续对前一个练习知识点进行训练，Zed 也会给出更多解释。如果仍然有困惑的地方，没关系，记下来，后面的练习会进一步讲解。总之，Keep going!

示例代码 Ex9:

# Here's some new strange stuff, remember type it exactly.
days = "Mon Tue Web Thu Fri Sat Sun"
months = "Jan\nFeb\nMar\nApr\nMay\nJun\nJul\nAug"

print "Here are the days: ", days
print "Here are the months:" , months

print """
There's something going on here.
With the three double-quotes.
We'll be able to type as much as we like.
Even 4 lines if we want, or 5, or 6.

小结

Ex9 提供了新知识: “\n”和三个双引号使用法。有两点注意事项:

Print 命令下， “\n” 如果被“％r”调用，那就只会显示“\n”,而不是换行。
三引号用法“”“使用中，引号不能隔开，必须连续输入。
