Description:

Those who come from the background of statically typed programming languages like typescript, golang etc, understands the importance of static typing. Luckily Python can be considered as both static and dynamic programming language. We can achieve static typing in python using 'typing' module. Python's Typing module has transformed the way developers approach static type checking and code quality in the language.

In this talk we are going to see the WHAT and the HOW of 'typing'. In simple words, WHAT specifies the behaviour of static typing and HOW specifies the implementation of static typing. We will discuss the fundamentals of:

• static typing
• type hints
• annotations
• generics
• protocols
• and showcase real-world examples of how the Typing module can transform your Python projects.

The talk timeline is as follows:

• Introduction (2 minutes)
• A question: Is python statically typed or dynamically typed? (1 minute)
• dropbox build mypy, google build pytype, facebook build pyre, microsoft build pyright, BUT WHY? (2 minutes)
• Brief overview of the importance of Static Typing (3 minutes)
• Basics understanding of types in python (2 minutes).
• Type hints to improve your projects (3 minutes)
• Type annotations (3 minutes)
• Generics and protocols (4minutes)
• How dropbox type checked 4 million lines of python code (https://dropbox.tech/application/our-journey-to-type-checking-4-million-lines-of-python) (5 minutes)
• QnA (5 minutes)

Attendee Takeaways: 1. After this talk, it is our hope that you will implement static typing in your projects and no longer get a lot of runtime errors as they will be detected earlier in the development phase. 2. The examples present in the talk will cover typing.Protocols, dataclass and a bunch of other commonly used functions of Python's typing module.

Note: The talk will be suitable for both beginner and intermediate level participants.

Prerequisites:

Basic understanding of newer versions of python
