assignments 21, and the sum of the four weights will be exactly 100. The weight of each category will be a non-negative number. Exam shifts will be ≥ 0. The program should be developed in a modular way using the functions, parameters, and returns value to eliminate redundancy. Give meaningful names to variables, and use proper indentation and whitespace. Follow Python's naming standards as specified in lecture. Localize variables when possible; declare them in the smallest scope needed. Include meaningful comment headers at the top of your program and at the start of each function. Limit line lengths to 100 chars. Consider to use some customized functions to reduce the code redundancy and promote the code reusability.
