Regular Expressions and Building Regexes in Python
In this course, you’ll explore regular expressions, also known as regexes, in Python. A regex is a special sequence of characters that defines a pattern for complex string-matching functionality.
String matching like this is a common task in programming, and you can get a lot done with string operators and built-in methods. At times, though, you may need more sophisticated pattern-matching capabilities.
In this course, you’ll learn:
- How to access the
remodule, which implements regex matching in Python
- How to use
re.search()to match a pattern against a string
- How to create complex matching pattern with regex metacharacters
- Explore more functions, beyond
re.search(), that the
- Learn when and how to precompile a regex in Python into a regular expression object
- Discover useful things that you can do with the match object returned by the functions in the
