Raw strings and multiline strings in Python

If a string contains many characters that need to be escaped, it can be cumbersome to escape each character. To avoid this, we can prefix the string to r  indicate that it is a raw string, and that the characters inside it do not need to be escaped. For example:

R ' \ (~_~)/\ (~_~)/'

However r‘...‘ , the notation cannot represent multiple lines of string, nor can it represent ‘ " a string containing and (why?). ）

If you want to represent multiple lines of string, you can use the ‘‘‘...‘‘‘ expression:

"Line 1Line 2Line 3"

The above string is represented in exactly the same way as the following:

' Line 1\nline 2\nline 3 '

You can also add the multiline string to a raw string by adding it in front  r  of it:

R ' ' Python is created by ' Guido '. It's free and easy to learn. Let's start learn Python in imooc! '
