Coding Assignments ( Python Functions )- Problems and Solutions

NOTE : The solutions are given at the last of this article. But try to write your code before taking the help of the solutions.

Problem 1 (Factorial)

Statement

Write a function to compute the factorial of a given number.

Explanation

def factorial(n):

        Complete the Body

a = factorial(4)

print(a) # 24

b = factorial(5)

print(b) # 120

Problem 2 (Sum of Digits)

Statement

Write a function sum_of_digits that takes an integer value as an argument and returns sum of digits of given number.

Explanation

def sum_of_digits(n):

        Complete the Body

a = sum_of_digits(123)

print(a) # 6

b = sum_of_digits(25)

print(b) # 7

Problem 3 (Prime Number)

Write a function is_prime(n) : It tests if n is a prime number (True) or not (False).

Explanation

        def is_prime(n):

Complete the Body

        a = is_prime(23)

        print(a) # True

        b = is_prime(15)   

        print(b) # False

Problem 4 (Highest Common factor or greatest common divisor)

Write a function hcf which takes 2 arguments and returns the greatest common divisor of these two numbers.

Explanation

        def hcf(a,b):

Complete the Body

        a = hcf(12,16)

Problem 5 (Lowest Common Multiple)

Write a function lcm which takes 2 arguments and returns the lowest common multiple of these two numbers.

        Explanation

        def lcm(a,b):

Complete the Body

        y = lcm(12,16)

Problem 6 (Armstrong number)

Statement

Write a function is_armstrong(n) : It tests if n is a Armstrong number (True) or not (False).

Note - Use google to know Armstrong number

def is_armstrong(n):

        Complete the Body

a = is_armstrong(153)

print(a) # True

b = is_armstrong(234)

print(b) # False
