A perfect number is one that is equal to the sum of its proper divisors, that is, sum of its positive divisors excluding the number itself. num = int(input("Enter any number: ")) sum = 0 for i in range(1, num): if(num % i == 0): sum = sum + i if (sum == num): ...
While loops exist in virtually all programming languages, the Pythonforloop function is one of the easiest built-in functions to master since it reads almost like plain English.In this tutorial, we’ll cover every facet of theforloop. We’ll show you how to use it with a range of example...
Python has a large and active community of developers who have created a wide range of modules and packages that extend the capabilities of Python. Some popular examples include NumPy for numerical computing, Pandas for data analysis, and Flask for web development. 12. What are global, protected...
A prime number is a natural number greater than 1 that has no positive divisors other 1 and itself. Although the simple definition, it occupies an important position in number theory, and the related theorems have become the backbone of modern information security. Problem 3: Largest prime facto...
is true for a large class of objects (often the natural numbers). We do this by first showing it to be true for a base case (such as the number 1) and then showing that it “carries over” from one object to the next (if it’s true for n –1, then it’s true for n). ...
