Designing With Immutability

Відео доповіді

Python is mutable to the core. Internals of objects and data structures are not only introspectable at runtime but also mostly modifiable. This is very useful and a big reason why Python is the language of our choice.

However, proper immutable collections do provide significant unique advantages, too. Python provides a few of those: strings, bytes, tuples, and frozensets. With the immutables package, you can also use an efficient Map implementation.

In this talk we'll go through a whirlwind tour of those advantages and how knowing about them can change how you design your software.
