CS306P Assignment 1 Solution Fall 2026

This assignment evaluates your proficiency in Python programming by implementing four specific functions. You will work with conditional logic, assignment operators, loops, and mathematical calculations. The tasks require you to write clean, modular code that processes inputs and returns results without using print or input statements inside the functions. You must submit all four functions within a single Python source file.

1. 1

   Task 1: Student Performance Evaluation

   5 marks

   Create a function named evaluate_student(marks, attendance) that determines academic status based on specific thresholds. You must use if-elif-else statements and the logical 'and' operator to check conditions in the exact order provided. The function should return a string indicating the status as 'Excellent', 'Satisfactory', 'Failed', or 'Short Attendance'.

2. 2

   Task 2: Update Bank Account Balance

   5 marks

   Implement a function named update_balance(balance) that modifies an initial account balance through a series of transactions. You are required to use assignment operators including += for deposits, -= for withdrawals and service charges, and *= to double the balance. The function must return the final calculated balance.

3. 3

   Task 3: Calculate Special Number Sum

   5 marks

   Write a function named sum_special_numbers(start, end) to calculate the sum of all integers divisible by 5 within a given range. You must use a for loop with range() and the modulus operator to identify qualifying numbers. If no numbers meet the criteria, the function should return 0.

4. 4

   Task 4: Calculate Repeated Product

   5 marks

   Develop a function named calculate_product(start, end) that computes the product of all consecutive integers between two provided values. You must use a for loop with range() to iterate through the sequence and accumulate the product. The function should return the final calculated product.

What to submit

One .zip file containing a single .py file with all four function definitions.
