Fixes #8754 and formatted code to pass ruff and black test. Also merged evaluate_postfix_notations.py and postfix_evaluation.py into postfix_evaluation.py which fixes #8724 and made sure it passes doctest Signed-off-by: Arijit De <arijitde2050@gmail.com> * Fixed return type hinting required by pre commit for evaluate function Signed-off-by: Arijit De <arijitde2050@gmail.com> * Changed line 186 to return only top of stack instead of calling the get_number function as it was converting float values to int, resulting in data loss. Fixes #8754 and #8724 Signed-off-by: Arijit De <arijitde2050@gmail.com> * Made the requested changes Also changed the code to make the evaluate function first convert all the numbers and then process the valid expression. * Fixes #8754, #8724 Updated postfix_evaluation.py postfix_evaluation.py now supports Unary operators and floating point numbers. Also merged evaluate_postfix_notations.py and postfix_evaluation.py into postfix_evaluation.py which fixes #8724.
