Refactor and Optimization:: Argument Table Formation:: Constants.py

[IIITM-Jay]

About

This PR deals with refactoring and optimization towards Argument Lookup Table (arg_lut) of constants.py. It focuses on optimizing the code with fewer lines keeping the objective same to provide better readability and concise comprehension.

Added/ Modified Changes

1. Changed the formation of arg_lut = {}: Used dictionary comprehension to form the required arg_lut
2. Read the CSV file and processes each row to convert the necessary values and build the dictionary.
3. Added appropriate comments
4. Avoided explicit iteration and assignment of values within a loop
5. Removed redundancy: prior declaration of a dictionary

Approach/ Technique/ Principles Used

1. Dictionary Comprehension:
   a. Offers syntax with lesser lines of codes: Dict Comprehensions , Reference taken
   {expression(variable): expression(variable) for variable, variable in input_set [predicate][, …]}
   b. Does exactly the same job without having prior declaration of the dictionary variable
