In programming, a loop is a control structure that repeatedly executes a block of code as long as a specified condition holds true. This repeated execution continues until the condition becomes false, at which point the loop terminates, and control passes to the next section of code. The use ...
A loop in computer programming is created when a sequence of instructions repeats until a certain terminating condition is reached. Typically, a definedprocessis completed -- such as getting an item of data and changing it -- and then a condition is checked, such as whether a counter has rea...
Python, one of the most versatile programming languages, is popular for data science applications, as well as web development, offers various ways to implement loops, particularly the for loop. This explainer will delve into the syntax and functionalities of for loops in Python, providing examples ...
In most programming languages, you'll come across three main types of loops: the "for" loop, the "while" loop, and the "do-while" loop. What's a "for" loop? A "for" loop is often used when you know the number of times you want to repeat a certain block of code. You specify...
A do-while loop is a particular kind of loop structure used in C++ that enables a block of code to be run repeatedly until a specific condition is satisfied. The condition for the loop is checked at the end of each iteration rather than at the beginning, which is a key distinction from...
Loops are among the most basic and powerful of programming concepts. A loop in a computer program is an instruction that repeats until a specified condition is reached. In a loop structure, the loop asks a question. If the answer requires action, it is executed. The same question is asked...

Q1. What is a for loop in Python? Statements are usually executed in the order in any programming language: the first statement in a function is executed first, then the second, and so on. You may find yourself in a position where you need to run a block of code multiple times....
