The Joy of Typing

# The Joy of Typing Python developers working with data are increasingly using "type annotations"—essentially labels that specify what kind of information (numbers, text, lists, etc.) a piece of code should handle—to make their work less error-prone and easier for teams to understand. This practice helps catch mistakes early and makes it simpler for colleagues to use someone else's code without confusion. If you work with data professionals or are curious about why they're adopting this practice, it's worth knowing that these labels are becoming a standard way to write more reliable, maintainable code.
