Purpose of re module
What is the purpose or application of re module?
Basically, data mining. Parsing strings and picking valuable organized data, meeting certain logical crteria, from sets of characters :) But there are also other non-obvious applications, like checking if a number is prime: https://code.sololearn.com/cgEoWC8lFuCk/#py
re module is used in regular expressions. By importing re module regular expressions can be used.
Can you show me an example to understand the purpose of it.
