Defining strings in Python

Strings can be ‘‘ expressed in or "" enclosed. What if the string itself contains ‘ ? For example, if we want to represent  I‘m OK  a string, we can say it in " " parentheses:

"I ' m OK"

Similarly, if a string is contained " , we can use it as a ‘ ‘ means of enclosing:

' Learn ' Python "in Imooc '

What if the string contains ‘ and contains both " ?

At this point, you need to "escape" some special characters of the string , and the Python string is \ escaped.

To represent a stringBob said "I‘m OK".
Because ' and ' can cause ambiguity, so we insert a representation before it that \ this is an ordinary character and does not represent the beginning of the string, so the string can be represented as

' Bob said \ ' i\ ' m ok\ '. '

Note: the escape character \ does not count toward the contents of the string.

The usual escape characters are:

\ n indicates a newline \ t means a tab \ \ means \ character itself

The following two lines of text are printed in Python's string representation:

Python is started in 1989 by "Guido".

Python is free and easy to learn.

Reference:

s = ' Python was started in 1989 by \ ' Guido\ '. \npython are free and easy to learn. ' Print S
