"""  Question 1

Write a program that will find all numbers which are divisible by 7 but are not a multiple of 5, between 2000 and 3200 (both included). The numbers obtained should be printed in a list.

Hint: Consider using the range(#begin, #end) method. """

""" Q 2 
 Write a program that can compute the factorial of a given number. (The factorial of n is the product of all positive integers less than or equal to n.) For example: For factorial(5)= 5 x 4 x 3 x 2 x 1 the result is 120 (i.e. factorial (0)=1). """

""" Q 3
With a given integer number n, write a program to generate a dictionary that contains (i, i*i) such that is an integral number between 1 and n (both included). Then, the program should print the dictionary. Suppose the following input is supplied to the program: 8 Then, the output should be: {1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}
