Question 2

What are type hints

Answer 2

Helps to document your code
Help catch certain errors
improve IDEs and linters
Doc strings aren’t helpful to linters and there’s no strict standard
Not a great idea for small throwaway scripts as there’s a performance hit and it adds developer time
Worth it if your writing unit tests and have a large code base
use <var>: <type>
used in parameters and return types</type></var>
