Now you have a deep understanding of how mutable and immutable data types internally work in Python. In general, mutable types allow in-place changes to their values, while immutable types don’t. Mutability is a fundamental feature that really influences which data types are appropriate for each specific problem.
Learning about mutable and immutable data types is, therefore, a vital skill to have as a Python programmer.
In this video course, you’ve learned:
- How mutability and immutability work under the hood in Python
- Which immutable and mutable built-in data types exist in Python
- What common mutability-related gotchas can affect your code and how to prevent them
- What techniques allow you to control mutability in custom classes
