the last two are used to convert them into backslashes in the programming language, convert them into two backslashes, and then escape them into a backslash in the regular expression. The native string in Python solves this problem well. In this example, the regular expression can be represented by r. Similarly, "\ d" matching a number can be written as r "\ d ". With the native string, mom doesn't have to worry about missing the backslash, and the written expression is more intuitive.4. Python

Very simply, we need to use the Re.compile method. For example Pattern = Re.compile (R ' Hello ') In the argument we pass in
