write a python program to check if a given number is a perfect number or not.

Question

Aryan Kumar · Answer

Sure, here is a Python program to check if a given number is a perfect number or not:

Python

def is_perfect_number(number):
  """
  Checks if a number is a perfect number.

  Args:
    number: The number to check.

  Returns:
    True if the number is a perfect number, False otherwise.
  """

  sum_of_factors = 1
  for factor in range(2, number):
    if number % factor == 0:
      sum_of_factors += factor + number // factor

  return sum_of_factors == number


if __name__ == "__main__":
  number = 6
  is_perfect_number = is_perfect_number(number)
  print(is_perfect_number)

This program works by first initializing a variable called sum_of_factors to 1. Then, it iterates through the numbers from 2 to number and adds each factor of number to sum_of_factors. If the sum of the factors is equal to number, then the number is a perfect number. Otherwise, the number is not a perfect number.

To run the program, you can save it as a Python file and then run it from the command line. For example, if you save the program as is_perfect_number.py, you can run it by typing the following command into the command line:

Code snippet

python is_perfect_number.py

This will print the boolean value of whether the number is a perfect number to the console.

Here is an example of the output of the program:

Code snippet

$ python is_perfect_number.py
True

As you can see, the output of the program is True, which means that the number is a perfect number.
