Differences Between Python's Mutable and Immutable Types (Summary)

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
