In this video we will walk through getting Alexa to say whatever you want! We will use Python and AWS lambda. Specifically we will walk through setup and how the code is structured. We will program a custom welcome message and then using intents build a simple application that gives us compliments!
Part 2 will focus on more complex back and forth interactions. It will cover the easiest way to debug your Alexa application. It will also cover session attributes and using intent slots.

In this video we go through all the fundamentals of using regular expressions (regexes) to match patterns in programming.
In this video we cover the following:
- Character Sets [a-zA-Z0-9]
- Quantifiers *, +, ?, {3,5}
- Metacharacters ^ . | $
- Character Classes b s w d
- Groups
- Lookahead & Lookbehind assertions
- and more!
There is a detailed timeline down below.
In a future video we will apply what we learn in this one to the Python programming language (re library) subscribe to not miss that!
