adding some type hints and few type checks

[farooqkz]

Hello there. I have added some Python type hints and a few type checks. Please let me know if I should change anything. Regards, Farooq.

So you are asking me to add type hints to all files?

yes, if it is something you'd like to do, it would be a great contribution. I would not add any explicit type checks however.

Currently, I don't have time to do the type hints for all of the API. And I suppose having type hints for some parts is better than not having them at all.

@cbrunet any other change required?

EDIT: Sorry I forgot it for a long time...
