Python, Assignment 1
A. Reinforcement of concepts / methods
Q1
(a) Write a Python function that takes a positive integer n, and returns the sum of the squares of all
the positive integers smaller than n.
(b) Write a Python function that takes a positive integer n, and returns the sum of the squares of all
the odd positive integers smaller than n.
Q2
What parameter values should be sent to the range constructor to produce a range with values:
(a) 60,70,80
(b) 4,2,0,-2,-4

Q3
Write a Python function that takes a sequence of integer values and determines if there is a distinct pair of
numbers in the sequence whose product is odd.
Q4
Write a Python function that counts the number of vowels in a given character string.
Q5
Write a Python program that takes as input three integers, “a”, “b” and “c”, from the console and
