Another week, another Code with Kylie video! Today we are talking about variables and mutability in data types.

This video is a part of the Code with Kylie series (learning python for the absolute beginner): https://www.youtube.com/playlist?list=PLkWv3oO4kHnuKi032yRRYgyQ4kgaNp6gs

Variables are values that can vary. We assign these in Python by declaring a variable name and assigning it a value through the assignment operator. I go over the rules in declaring variable names in this video. I show you how to visualize variable assignments with diagrams where the variables point to values in memory.

Mutability is the ability to change. Basically, in Python, we have mutable and immutable data types. Mutable data types include lists, sets, and dictionaries. We can change the items in the collection without recreating the entire collection again. Meanwhile, immutable data types include strings, numbers, booleans, and tuples.

In this video, I also talk about when you should use immutable data types and when you should use mutable data types. We use these for different reasons!
