In computer science, a loop variant is a mathematical function defined on the state space of a computer program whose value is monotonically decreased with respect to a (strict) well-founded relation by the iteration of a while loop under some invariant conditions, thereby ensuring its termination. A loop variant whose range is restricted to the non-negative integers is also known as a bound function, because in this case it provides a trivial upper bound on the number of iterations of a loop before it terminates. However, a loop variant may be transfinite, and thus is not necessarily restricted to integer values. A well-founded relation is characterized by the existence of a minimal element of every non-empty subset of its domain. The existence of a variant proves the termination of a while loop in a computer program by well-founded descent. A basic property of a well-founded relation is that it has no infinite descending chains. Therefore a loop possessing a variant will terminate after a finite number of iterations, as long as its body terminates each time. A while loop, or, more generally, a computer program that may contain while loops, is said to be totally correct if it is partially correct and it terminates. (Wikipedia).

This Python tutorial will help you understand what is for loop and how to use for loop in Python. In programming, statements are executed sequentially. The first statement in a code is executed first, followed by the second one, and so on. There may be a situation when you need to execute
Basic intro to answer the question, "What's a Loop?" If there's a set of data, (we'll use an array for this example, but it doesn't have to be,) and you want to perform the same manipulation to every piece in that set of data, you can use something called a loop. Loops have some complex

What are loops in graph theory? Sometimes called self loops, a loop in a graph is an edge that connects a vertex to itself. These are not allowed in what are often called "simple graphs", which are the graphs we usually study when we begin studying graph theory. In simple graphs, loop ed

The two distinctive loops we have in Python 3 logic are the "for loop" and the "while loop." Both of them achieve very similar results, and can almost always be used interchangeably towards a goal. Many times it comes down to programmer preference, or is reliant on efficiency. Generally, t
