What is for loop explain with example Python?
A for loop is a programming concept that, when it’s implemented, executes a piece of code over and over again “for” a certain number of times, based on a sequence. In contrast to the while loop, there isn’t any condition actively involved – you just execute a piece of code repeatedly for a number of times.
How do you use a for loop?
A “For” Loop is used to repeat a specific block of code a known number of times. For example, if we want to check the grade of every student in the class, we loop from 1 to that number. When the number of times is not known before hand, we use a “While” loop.
What are the types of loops in Python?
Python has two types of loops: the for loop and the while loop. Loops have variables which change their values in every execution of the loop’s body and these variables have to be used as a condition either in the loop’s head or in the body to break the flow.
What is an example of a loop in programming?
The exact looping process and initial structuring varies between programming languages. In SQL, for example, a programmer may script these structures and execute them either as a server nested loop that is called remotely or as one on a client machine that is executed locally.
What does while loop mean in Python?
While Loop: In python, while loop is used to execute a block of statements repeatedly until a given a condition is satisfied. And when the condition becomes false, the line immediately after the loop in program is executed.
What is a loop statement in Python?
A loop statement allows us to execute a statement or group of statements multiple times. The following diagram illustrates a loop statement −. Python programming language provides following types of loops to handle looping requirements. Repeats a statement or group of statements while a given condition is TRUE.
