Duplicate solutions for postfix notation evaluation.

[amirsoroush]

Feature description

Hi,
I noticed there are two files for evaluating postfix notation which are:

1. ...stacks/evaluate_postfix_notations.py
2. ...stacks/postfix_evaluation.py

The latter has bunch of print statements explaining the steps which is pretty useful for educational purposes but not in production. (It can be changed to have a verbose=True parameter for prints for example.)

Is having these two files intentional or we should combine them?

[tianyizheng02]

I highly doubt that having two files was intentional, especially since their algorithms appear to be basically identical. My guess is that a duplicate implementation was unknowingly approved and merged. Personally, I'm in favor of combining the two implementations into a single file.

Hi @amirsoroush @tianyizheng02 ,

I rectified this issue and #8754 in PR #8787.

Could you please review the PR and let me know if there is anything else that needs to be done?

Thanks
