Create a Python program to print numbers from 1 to 10 using a for loop. After being dubbed “sexiest job of the 21st Century” by Harvard Business Review, data science has stirred the interest of the general public. Also works for multiplication. A perfect number is a number whose factors, including the number itself, sum up to twice the number. 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). 0 … Python Program to find Even Numbers from 1 to 100 without If Statement. How can I become a data scientist? But, we altered the Python For Loop to eliminate If block.. Create a Python program to print numbers from 1 to 10 using a while loop. A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times. We are only going to print perfect numbers in a range in this tutorial. For example,6 is a perfect number since its factors (1, 2, 3, 6) sum up to 12. Ad by DataCamp. Solution. In programming, Loops are used to repeat a block of code until a specific condition is met. Python, 17 lines Check it out here: Check whether a number is a perfect number or not - Python *You should check it because we are not going to again discuss the procedure to check a number for perfect number, because then the article would be too long. For python 2.x, to use print as a function rather than a statement (i.e. If you observe the below Python program, we started the range from 2, and we used the counter value is 2.It means, for the first iteration number is 2, second iteration number = 4 (not 3) so on. The While loop loops through a block of code as long as a specified condition is true. Python 2.x. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Python Math: Find perfect squares between two given numbers Last update on February 26 2020 08:09:18 (UTC/GMT +8 hours) 6 is a Perfect Number: The divisors of 6 are 1, 2, 3 and 6. The examples of some other perfect numbers are 28, 496, and 8,128. Solution. Write a Python function to check whether a number is perfect or not. Examples of Perfect Numbers with the Sum of their Proper Divisors. Interestingly, every answer here mentions the use of modulo. It also means that perfect numbers are very rare. print()) the followring needs to be imported at the start of the script. To Learn more about working of While Loops read: How To Construct While Loops In Python How can I write a function in Python to print all perfect numbers between 1 and 10000? Python Functions: Exercise-11 with Solution. The previous code works for Python 3.x as mentioned in the comments by @idjaw. * For example: In the range of 3 to 100, This Python even numbers from 1 to 100 examples is the same as above. perfect number are those in which the whose divisors proper sum is equal to the number.for eg: 6 has 1,2,3 as the proper divisors.sum of 1,2, and 3 is 6. Note: I += 1 in python is simpler than doing I=I+1. In programming, Loops are used to repeat a block of code until a specific condition is met.
