15. Factors Generator

Write a Python program to create a generator function that generates all factors of a given number.

Sample Solution:

Python Code:

def create_factors(n):
    for i in range(1, n+1):
        if n % i == 0:
            yield i

# Accept input from the user
n = int(input("Input a number: "))

# Create the generator object
factors_gen = create_factors(n)

# Generate and print all factors
print("Factors of", n)
for factor in factors_gen:
    print(factor, end = ", ")

Sample Output:

Input a number: 1000
Factors of 1000
1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 125, 200, 250, 500, 1000,

Input a number: 56
Factors of 56
1, 2, 4, 7, 8, 14, 28, 56,

Input a number: 97
Factors of 97
1, 97,

Explanation:

In the above exercise -

We define the generator function create_factors() that takes a number n as input. It iterates over the range from 1 to n+1 and checks if n is divisible by each number. If it is, it yields that number.

Next we accept input from the user to determine the number for which we want to find factors. We create the generator object factors_gen and use it to generate and print all factors of the given number.
