Definite iteration loops are frequently referred to as for loops because for is the keyword that is used to introduce them in nearly all programming languages, including Python. Historically, programming languages have offered a few assorted flavors of for loop. These are briefly described in the following sections.

A definite loop and an infinite loop are two types of loops used in programming. A definite loop is a loop that executes a specific number of times, as determined by the programmer. It is often used when the number of iterations is known in advance or when a specific condition needs to be met. On the other hand, an infinite loop is a loop that ...

Dec 19, 2023 · The simplest kind of loop is called a definite loop. This is a loop that will execute a definite number of times. That is, at the point in the program when the loop begins, Python knows how many times to go around (or iterate) the body of the loop. For example, the Chaos program from Chapter 1 used a loop that always executed exactly ten times.
The variable friend changes for each iteration of the loop and controls when the for loop completes. The iteration variable steps successively through the three strings stored in the friends variable.

Definite Loops REPEAT n TIMES 1. The REPEAT n TIMES loop is used when you know exactly how many times to repeat the loop, namely n times. The value of n cannot be changed or referred to inside the loop body. Because it will always execute exactly n times, this is sometimes referred to as a definite loop.
