Use typing in examples

[ttu]

Most of the examples are missing type hints.

No need to fix all examples in a single PR, but adding typing even to a single example is already a great help!

Hey , can I work on this issue?

[ttu]

@chandu-jadhav Sure!

As mentioned in the description, no need to add typing to all examples at once in a single PR, but you can modify one example, create a PR and ask for feedback.

Let me know if you have some questions.
