Python Learning-Output a string with special characters

If there are special characters in a string, such as "\ n", we have two ways to automate the output of such a string.

1. Add the transfer character before these special characters \, which is used by most programming languages.

2. Add r before this string, for example: str = "Let's Go", the string with a ', to output, you can change this string to str = r "Lets ' Go". This allows you to output the original string without a transfer character. But one thing to note is that in this way, the end of the string cannot be added \, and if it is str = r "Let's Go\", it will report a syntax error.
