They are a different way of describing a string in your source code. You can however, create a new raw string from s, like this: raw strings apply only to string literals. Using the same text example, add the r prefix before the string. For instance, H will be represented as code point U+0048. What we need to do is just put the alphabet r before defining the string. If a backslash ( \) is in the string, the raw string We will prefix r before using them to achieve the same.
