Python programming solutions for basic computational problems

Understanding fundamental programming tasks within Python is essential for developing computational thinking and problem-solving skills. This report provides a comprehensive solution to the assigned tasks, illustrating how Python can be used to implement straightforward algorithms that are foundational in computer science education.

Calculating the Number of Nintendo Wiis an Individual Can Afford

The initial task involves writing a Python program that prompts the user to input their total amount of money. The program then calculates how many Nintendo Wiis the user can purchase, assuming a fixed price for each Wii. Additionally, it computes how much more money the user needs to buy an additional Wii, if they cannot afford one with their current funds.

To implement this, we define the price of one Nintendo Wii as a constant, say $300. The program then asks the user for their total money and converts the input into a numerical value. It calculates the number of Wiis the user can buy by performing integer division of the total amount by the price per Wii. To find out how much more money is needed to purchase an additional Wii, it checks whether the user's funds are sufficient for one more Wii; if not, it determines the difference between the Wii's cost and the user's current funds.

This task highlights basic operations in Python, including input collection, type conversion, integer division, and conditional statements.

Optional Problems and Their Implementations

Calculate the Area of a Triangle

The program prompts the user for the base and height of a triangle, then computes the area using the formula: (1/2) base height. This demonstrates user input handling, arithmetic operations, and output display in Python.

Calculate the Greatest Common Divisor (GCD)

The GCD of two positive integers can be computed using Euclid's algorithm, which involves iterative modulus operations until the remainder becomes zero. This recursive or iterative approach exemplifies algorithm efficiency and control structures in Python.

Calculate the Least Common Multiple (LCM)

The LCM of two positive integers can be derived from their GCD using the relationship: LCM(a, b) = |a * b| / GCD(a, b). Implementing this requires calling the GCD function and performing division, illustrating function composition and mathematical operations.

Solve the Expression (x + y)^2

The task involves defining variables x and y with numerical inputs, then computing the square of their sum. Using arithmetic operations and proper input parsing in Python, this problem emphasizes expression evaluation and output formatting.

Calculate the Distance Between Two Points

The distance formula between points (x1, y1) and (x2, y2) is derived from the Pythagorean theorem: sqrt((x2 - x1)^2 + (y2 - y1)^2). The program prompts the user for the coordinates, converts inputs to floating-point numbers, computes the differences, squares them, sums them, and finally applies the square root function from Python's math module. This task demonstrates the integration of mathematical functions and user interaction.

Conclusion

This set of Python programming exercises encapsulates fundamental computational concepts, including arithmetic computations, control flow, user input/output, and algorithm implementation. Mastery of these tasks provides a crucial foundation for more advanced programming skills, problem-solving, and algorithm development in the realm of computer science.
