Day 17 : Python Program to Find all the Divisors of an Integer

 

def check_divisor(number):

    number = abs(number)

    divisors = []

    for i in range(1, number + 1):

        if number % i == 0:  

            divisors.append(i)

    return divisors

number = int(input("Enter an integer: "))

divisors = check_divisor(number)

print(f"The divisors of {number} are: {divisors}")

Code Explanation

1. Function Definition

def check_divisor(number):

def: Declares a new function.

check_divisor: The name of the function, which checks for all divisors of a given number.

number: Input parameter representing the number for which divisors are to be found.

2. Taking Absolute Value

    number = abs(number)

abs(number): Returns the absolute value of the number (i.e., removes the negative sign if the number is negative).

Example: If number = -12, abs(-12) becomes 12.

This ensures that the logic for finding divisors works even if the input is a negative number.

3. Initializing an Empty List

    divisors = []

divisors: An empty list to store all divisors of the given number.

4. Iterating Through Potential Divisors

    for i in range(1, number + 1):

for i in range(1, number + 1):

Starts a loop to check all numbers (i) from 1 to number (inclusive).

range(1, number + 1): Generates all integers from 1 to number.

5. Checking for Divisors

        if number % i == 0:

number % i: Computes the remainder when number is divided by i.

If the remainder is 0, it means i is a divisor of number.

6. Adding Divisors to the List

python

Copy code

            divisors.append(i)

divisors.append(i): Adds the number i to the divisors list if it is a divisor of number.

7. Returning the List of Divisors

    return divisors

return divisors: Returns the complete list of divisors after the loop finishes.

8. Taking User Input

number = int(input("Enter an integer: "))

input("Enter an integer: "): Displays a prompt and reads the user’s input as a string.

int(): Converts the string input into an integer.

number: Stores the user-provided number.

9. Calling the Function and Printing the Result

divisors = check_divisor(number)

print(f"The divisors of {number} are: {divisors}")

check_divisor(number): Calls the check_divisor function with the user-provided number.

divisors: Stores the list of divisors returned by the function.

print(f"..."): Displays the result in a user-friendly format using an f-string.
