For loop

For loop’s technical definition:

The for loop is merely a programming function that iterates a statement or a set of statements depending on predefined boundaries under predetermined conditions, much like all the other functions.

Keep in mind that the statement the loop iterates must appear inside the loop’s body.

Iteration in terms of loops refers to repeatedly running a section of code. The main difference is that in programming, the iteration is dependent on specific circumstances, and when those circumstances are met, the iteration terminates and the compiler continues.

An example of the song’s playlist could make the concept of the loop simple to understand for a novice or layperson. When we put a song on repeat, which we do when we like it, it will play continuously. The similar idea is applied in programming, where a section of code is designated for looping and continues to run until the specified condition is satisfied. You must believe that the song in the playlist plays indefinitely until we stop it. The identical situation can be created with loops, and if we set a condition that the loop is unable to satisfy, it will continue to iterate indefinitely until forcibly halted.

A situation where a loop might be useful for us is when a lot of data needs to be printed on the screen but creating that many printing statements by hand might be challenging or even impossible. In addition, loops are useful for searching data in dictionaries, lists, and tuples.

Why are loops used?

Loops can be used to simplify complex tasks.

Less code is needed for our program.

Less code means less possibility of error, which saves time.

can create program that are almost hard to create

Loops can be used to streamline program that need too many iterations, such as searching and sorting algorithms.

Instead than relying on whether a statement is true or not, a for loop basically depends on the elements it must iterate. The process of writing a loop varies depending on the programming language; while it may be a little sophisticated and challenging for a beginner to understand in Java and C, it is straightforward and simple in Python. Simply declare a variable and use the verbs “for” and “in” to use it to print the output during several iterations.

Benefits of loops

Code reuse is made possible.

The code only needs to be written once; we don’t need to repeat it often.

Data structures like list, dictionary, and tuple are all accessible to us.

Most of the searching algorithms are used in loops.
