Assignment 3: Module 4 - Functions & Modules in Python

Task 1: Calculate Factorial Using a Function

This Python script defines a function named factorial that takes a number as an argument and calculates its factorial using recursion. The script then calls the function with a user-provided number and prints the output.

Example Usage

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n-1)

number = int(input("Enter a Number: "))
print(f"Factorial of {number} is {factorial(number)}")

Expected Output

Enter a Number: 5
Factorial of 5 is 120

Task 2: Using the Math Module for Calculations

This Python script asks the user for a number as input and uses the math module to calculate the square root, natural logarithm (log base e), and sine (in radians) of the number. The calculated results are then displayed.

Example Usage

import math

number = float(input("Enter a number: "))

sqrt_num = math.sqrt(number)
log_num = math.log(number)
sine_num = math.sin(number)

print(f"Square root of {number} is {sqrt_num}")
print(f"Natural logarithm (log base e) of {number} is {log_num}")
print(f"Sine of {number} (in radians) is {sine_num}")

Expected Output (for input 25)

Enter a number: 25
Square root of 25 is 5.0
Natural logarithm (log base e) of 25 is 3.2188758248682006
Sine of 25 (in radians) is -0.13235175009777303
