As it turns out, computers like numbers, and humans like words. And teaching computers how to do words good, and understand which parts of words you want done, is hard. Regular expressions are a powerful cross-language tool for parsing and digesting text in a way that a computer can understand.
We’ll look at:
- Regular Expression Syntax
- Pattern Matching with Wildcards
- Using character classes to simplify expressions
- Parsing real motion sensor/temp/humidity data using Regexes
- Parsing Advent of Code input using regexes
- And more
This week had no slides.
