The importance of a do-while loop is that it is a post-test loop, which means that it checks the condition only after is executing the loop block once. 1. Python Loop – Objective. In this Python Loop Tutorial, we will learn about different types of Python Loop. Here, we will study Python For Loop, Python While Loop, Python Loop Control Statements, and Nested For Loop in Python with their subtypes, syntax, and examples.
To keep a computer doing useful work we need repetition, looping back over the same block of code again and again. This post will describe the different kinds of loops in Python. For Loop The for loop that is used to iterate over elements of a sequence, it is often used when you have a piece of code which you want to repeat "n" number of time. Loops are important in Python or in any other programming language as they help you to execute a block of code repeatedly. You will often come face to face with situations where you would need to use a piece of code over and over but you don't want to write the same line of code multiple times. Greg Ewing The trouble with repeat-until is that the entire loop always executes at least once, even if the stopping condition is true at the outset. The more experience you get at programming, the more you come to realise that situations where this is the right behaviour are extremely rare, and in the vast majority of cases, writing a loop that way is asking for a bug. Python while Loop Examples Understand the while-loop. While continues until a terminating condition is met. While. Sometimes a loop must continue until its expression evaluates to false. The body is not needed. In C-like languages, a semicolon would be used for an empty line. 12/01/2017 · How To Construct For Loops in Python 3.
