Answer :
The code provides a RationalNumber class with arithmetic operations and a power computation function, along with a menu-driven user interface for handling rational numbers, including user login and password verification.
To achieve the requirements outlined in the task, we can design the RationalNumber class as a separate module and implement a text-based menu-driven user interface in the main application. Additionally, we can include the option for user login and password verification for credit grade and add functions to compute rational numbers to the power of n for a distinction grade.
Let's start by creating the RationalNumber class as a separate module:
rational_number.py
python
class RationalNumber:
def __init__(self, a, b):
self.a = a
self.b = b
def simplify(self):
# Function to simplify the rational number to its simplest form
# Implement the logic to find the greatest common divisor (GCD) and simplify the fraction.
def __add__(self, other):
# Overloaded addition operator to add two rational numbers
# Implement the logic to add two rational numbers and return the result.
def __sub__(self, other):
# Overloaded subtraction operator to subtract two rational numbers
# Implement the logic to subtract two rational numbers and return the result.
def __mul__(self, other):
# Overloaded multiplication operator to multiply two rational numbers
# Implement the logic to multiply two rational numbers and return the result.
def __truediv__(self, other):
# Overloaded division operator to divide two rational numbers
# Implement the logic to divide two rational numbers and return the result.
def power(self, n):
# Function to compute the rational number to the power of n
# Implement the logic to calculate rational number raised to a positive, negative, or zero power.
# Simplify the result and return it.
def __str__(self):
return f"{self.a}/{self.b}"
Next, let's create the main application with the user interface:
main.py
python
from rational_number import RationalNumber
def user_login():
# Function to handle user login and password verification
# Implement the logic to check username and password from a file and provide three consecutive trials.
def main():
user_login() # Uncomment this line for credit grade requirement
print("Welcome to the Rational Number Calculator!")
# Initialize an empty list to store rational numbers
rational_numbers = []
while True:
print("\nMenu:")
print("1. Enter a new rational number")
print("2. Perform calculations")
print("3. Exit")
choice = int(input("Enter your choice (1/2/3): "))
if choice == 1:
# Get user input for a new rational number
a = int(input("Enter the numerator: "))
b = int(input("Enter the denominator: "))
rational = RationalNumber(a, b)
rational_numbers.append(rational)
elif choice == 2:
if not rational_numbers:
print("No rational numbers entered yet.")
continue
print("\nAvailable Rational Numbers:")
for i, rational in enumerate(rational_numbers):
print(f"{i+1}. {rational}")
index = int(input("Enter the index of the first rational number: ")) - 1
n = int(input("Enter the power (n) to compute: "))
if 1 <= index < len(rational_numbers):
result = rational_numbers[index].power(n)
print(f"Result: {result}")
else:
print("Invalid index.")
elif choice == 3:
print("Exiting the Rational Number Calculator. Goodbye!")
break
else:
print("Invalid choice. Please try again.")
if __name__ == "__main__":
main()
In this implementation, the RationalNumber class provides the functionalities required to handle rational numbers, including simplification, basic arithmetic operations, and computation of rational numbers to the power of n. The main application offers a text-based menu-driven user interface for the user to interact with the RationalNumber class.
To achieve a credit grade, you can uncomment the user_login() function in the main.py file. This function handles user login and password verification, as described in the task.
For a distinction grade, you can implement the power() method in the RationalNumber class to compute rational numbers to the power of another rational number. The implementation should handle simplifying the result to its simplest form.
Please note that the code provided is a basic outline of how the application should work. You may need to further enhance and validate the input handling, error handling, and file handling, depending on the specific requirements and complexities of the application.
