Definition of strings in Python

We explained earlier what a string is. Strings can be represented by '' or "".

What if the string itself contains '? For example, if we want to express the string I'm OK , we can use <span style="color:rgb(255,0,0);">" "</span> to express:

"I'm OK"

Copy after login

Similarly, If the string contains ", we can use ' ' to express:

'Learn "Python" in imooc'

Copy after login

If the string contains both ' What should I do if also contains "?

At this time, you need to "escape" some special characters in the string. Use \ to convert the Python string. righteous.

要表示字符串 Bob said "I'm OK".
由于 ' 和 " 会引起歧义，因此，我们在它前面插入一个\表示这是一个普通字符，不代表字符串的起始，因此，这个字符串又可以表示为

'Bob said \"I\'m OK\".'

Copy after login

注意：转义字符 \ 不计入字符串的内容中。

常用的转义字符还有：

\n 表示换行
\t 表示一个制表符
\\ 表示 \ 字符本身

Copy after login
