How do you check if a number is a perfect number in python?
Python Functions: Exercise-11 with SolutionWrite a Python function to check whether a number is perfect or not. Show According to Wikipedia : In number theory, a perfect number is a positive integer that is equal to the sum of its proper positive divisors, that is, the sum of its positive
divisors excluding the number itself (also known as its aliquot sum). Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (including itself). Sample Solution:- Python Code:
Sample Output: True Pictorial presentation: Flowchart: Visualize Python code execution:The following tool visualize what the computer is doing step-by-step as it executes the said program: Python Code Editor: Have another way to solve this solution?

Write a Python program to print the even numbers from a given list. Playing with numbers is something that we are doing since our childhood. The basic arithmetic operations performed on numbers generate valuable results. In the voyage of learning, we must give more emphasis to the logic develop in mathematics as they become the foundation of programming. In this article, let us discuss what is a perfect number, what are the steps to determine whether a number is perfect or not, and finally, we shall see how its program can be written in Python. So, let's get started… First, let us understand what is a perfect number? A perfect number is a number in which the sum of the divisors of a number is equal to the number. Make sure that we have to exclude the number when we are calculating the sum of divisors. Now, we will see what are the steps involved in determining the perfect number.
It's time to have a look at the Python program- Example - Output: Enter the number: 6 The entered number is a perfect number Enter the number: 25 The entered number is not a perfect number Explanation - In the program given above, we have-
Let us have a look at another program where we will implement the same with the help of a function. Example - 2: Output: Explanation - In this program, we have used steps similar to the ones we discussed in the previous example, the only difference is here we have defined a function and called it by providing a value. Because the return statement is present at the end of a function definition, it gives the value as True and False. So, in this tutorial, we learned about perfect numbers, the process that we must follow to determine whether the given number is perfect or not, and at the end discussed its implementation in Python. How do you check if a number is perfect in Python?Example -. num=int(input("Enter the number: ")). sum_v=0.. for i in range(1,num):. if (num%i==0):. sum_v=sum_v+i.. if(sum_v==num):. print("The entered number is a perfect number"). How do you check if a number is a perfect?A number is a perfect number if is equal to sum of its proper divisors, that is, sum of its positive divisors excluding the number itself. Write a function to check if a given number is perfect or not. ... . A Simple Solution is to go through every number from 1 to n-1 and check if it is a divisor.. What is meant by perfect number in Python?Python Functions: Exercise-11 with Solution
Equivalently, a perfect number is a number that is half the sum of all of its positive divisors (including itself). Example : The first perfect number is 6, because 1, 2, and 3 are its proper positive divisors, and 1 + 2 + 3 = 6.
How do you find the perfect number between two numbers in Python?Python Program
n = int(input("Enter a number")) sum = 0 for i in range(1, n): if n%i == 0: sum += i if n == sum: print(f"{n} is a Perfect number") else: print(f"{n} is not a Perfect number"); As in C++ and Python, you can also implement the same program in Java. 8 is not equal to 10. So, 10 is not a perfect number.
