笨方法学python(本文为阅读时从此书摘录的笔记) 第二天

6.

单引号、双引号括起来的东西为字符串

%r多功能占位符会在替代它的字符串前后加上单引号

第一次见的写法：

x="There are %d types of people."%10

print("I said:%s"%x)

hilarious=False
joke_evaluation="Isn't that joke so funny?! %r"

print(joke_evaluation%hilarious)

7.

print("."*10)

输出结果为：..........

8.

formatter="%r %r %r %r"

print(formatter%(1,2,3,4))

答案：因为第三个字符串里有单引号

9.

print(""" """)之间的文字将被原样保留(转移字符除外)，并在结尾自动换行

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.""")

输出结果：

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.

10.

        *Cat food
