 Write a program to input the value of x and n and print the sum of the
following series:

 Determine whether a number is a perfect number, an Armstrong number
or a palindrome.
 Input a number and check if the number is a prime or composite number.
 Display the terms of a Fibonacci series.
 Compute the greatest common divisor and least common multiple of two
integers.

Project

 The aim of the class project is to create something that is tangible and
useful using Python. This should be done in groups of five to six students
and should be started by students at least 3 months before the submission
deadline. The aim here is to find a real-world problem that is worthwhile
to solve.
 Students are encouraged to solve general and the school level problems,
such as-create a calculator for general calculations, create a project to
solve mathematical problems like area / perimeter of circle / square /
rectangle etc., create a project to calculate the result of a student, create a
project to calculate the net bill for sale with discount, create a database to
store the student information etc. Students are also encouraged to use
comments properly in the programs.
 To do some of these above-mentioned project suggestions, some
additional learning is required. This should be encouraged. Students
should know how to teach themselves.
 The students should be sensitized to avoid plagiarism and violations of
copyright issues while working on projects. Teachers should take
necessary measures for this.
