[CandiedCode]

• remove unused imports
• remove unnecessary f-strings
• remove use of in with literals
• add doc string and type hinting support to pytorch_sentiment_analysis notebook
• use magic command for %pip to make sure packages are installed within the current kernel.
• use lazy concatenation for loggers

Most of the changes looks good on a quick glance. Do you mind updating the notebook without pushing the new output? We would like to keep the original demos intact.

@iamfaisalkhan I reverted the output of the notebook. Would it make sense to have docker support to make it possible to have reproducible notebook runs, that way it's not tied to a users specific setup?

If you are open, I can do a devcontainer, which github also supports, setup or we can just have a simple dockerfile as an alternative seperate from this pr.

What do you think @iamfaisalkhan?

That's a good idea. Open to either devcontainer or Docker file in a separate PR. The These changes look good to me.
