String learning Summary

String prefix with R: indicates the original string

String prefix with u: unicode encoding

Single quotation marks, double quotation marks, and three quotation marks (single quotation marks and double quotation marks )... Meaning:

In python, strings can be enclosed in single quotes or double quotes. These two methods are equivalent.

The Python three quotation marks form is used to input multiple lines of text. That is to say, the content entered between the three quotation marks will be reserved as is, and the single and double quotation marks in the form do not need to be escaped, invisible characters such as/N and/t are retained. The advantage is that you can replace some multi-line text.
