Apr 24, 2023 · While loop is used when the number of iterations is not known in advance or when we want to repeat a block of code until a certain condition is met. For loop require a sequence to iterate over. While the loop requires an initial condition that is tested at the beginning of the loop.

For loops are generally used when the number of iterations is known (the length of an array for example), and while loops are used when you don't know how long it will take (for example the bubble sort algorithm which loops as long as the values aren't sorted)

Aug 30, 2023 · This Python tutorial explains what is for loop vs while loop in Python with examples using different basis in detail like syntax, initialization, termination, etc.

In Python, you can use for and while loops to achieve the looping behavior. For example, here is a simple for loop that prints a list of names into the console. And here is a simple while loop that prints numbers from 0 to 5: In this guide, you are going to learn.

Jul 11, 2021 · For loop – For loops are used to sequentially iterate over a python sequence. When the sequence has been iterated completely, the for loop ends and thus executes the next piece of code. The while loop statement is used to repeat a block of code till a condition is fulfilled.

Apr 19, 2024 · Both for loops and while loops are control flow structures in programming that allow you to repeatedly execute a block of code. However, they differ in their syntax and use cases. It is important for a beginner to know the key differences between both of them.

Mar 8, 2025 · Let us learn how to use for loops in Python for sequential traversals with examples. Explanation: This code prints the numbers from 0 to 3 (inclusive) using a for loop that iterates over a range from 0 to n-1 (where n = 4). We can use for loop to iterate lists, tuples, strings and dictionaries in Python.

Learn the key differences between for loops and while loops in Python, including syntax, use cases, and best practices.

May 8, 2023 · For loop is used in Python to iterate through the elements of an iterable object and execute some statements. While loop is used to execute statements in Python until a condition remains True. We cannot execute for loop based on a condition or until a condition is true.

Dec 12, 2022 · The major difference between for loop and while loop is that for loop is used when the number of iterations is known, whereas execution is done in a while loop until the statement in the program is proved wrong.
