Session 2 - “Regular Expressions” of my Programming with Text video series.
In this video I introduce Regular Expressions. What are they and how are they used?
In this video I discuss meta-characters: what are they and what role do they play in regular expressions?
In this video, I explain character classes which are a way of matching a selection of characters in a regular expression.
In this video I discuss capturing parentheses and how they are used to create numbered groups that referenced in a find/replace operation.
In this short tutorial, I explain the concept of “back references” and explore how they are used to match the characters previously matched by capturing parentheses (groups) in a regular expression (regex).
This video covers
replace(). The function allows you to search for a string (by matching a regular expression) and replace that string.
In this short video I discuss a creative assignment around the topic of Regular Expressions in Week 2 of “Programming from A to Z”.
