《笨办法学python3-Learn Python 3 the HARD WAY》-习题9 打印，打印，打印

学习内容：

# Here's some new strange stuff, remember type it exactly.

days = "Mon Tue Wed Thu Fri Sat Sun"
months = "Jan\nFen\nMar\nApr\nMay\nJun\nJul\nAug"

print ("Here sre 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 muchas we like.
Even 4 line if wu want, or 5, or 6.
""")

运行结果：

知识点：

1. 换行符
   \n：换行符
   例：字符串后面跟着\n 就是下一个字符串换行的意思。

months = "Jan\nFen\nMar\nApr\nMay\nJun\nJul\nAug"
print (months)

2. 多行注释符
“”“字符串内容”"" ：主要体现在跨行的字符串上，会包含两个界定符号之间的所有字符，包括看得见和看不见的，例如回车换行等。
可以理解为在三个引号之间的字符串你是怎么输入的，打印时就如何输出，减少了\n这类的换行符。
注：两头的三个引号之间不能有空格。
例：

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