The Joy of Computing using Python Programming Assignment

Question 1

Write the following functions:

(1) factors: accept a positive integer n as argument. Return the set of all factors of n.

(2) common_factors: accept two positive integers a and b as arguments. Return the set of common factors of the two numbers. This function must make use of factors.

(3) factors_upto: accept a positive integer n as argument. Return a dict D, whose keys are integers and values are sets. Each integer in the range [1,n], endpoints inclusive, is a key of D. The value corresponding to a key, is the set of all factors of key. This function must make use of factors.

The idea we are trying to bring out here is to make use of pre-defined functions whenever needed.

Solution:

def factors(n):

    factor_set = set()

    for ips in range(1, n + 1):

        if n % ips == 0:

            factor_set.add(ips)

    return factor_set

def common_factors(a, b):

    factors_a = factors(a)

    factors_b = factors(b)

    return factors_a.intersection(factors_b)

def factors_upto(n):

    factors_dict = {}

    for i in range(1, n + 1):

        factors_dict[i] = factors(i)

    return (factors_dict)
