Apr 24, 2023 · For loop is used to iterate over a sequence of items. While loop is used to repeatedly execute a block of statements while a condition is true. For loops are designed for iterating over a sequence of items. Eg. list, tuple, etc.

First of all there are differences between the for loop in python and in other languages. While in python it iterates over a list of values (eg: for value in [4,3,2,7]), in most other languages (C/C++, Java, PHP etc) it acts as a while loop, but easier to read.

Aug 30, 2023 · In this Python tutorial, I will explain what is the For loop vs while loop in Python. In the process, we will see, what is meant by Python for loop and while loop with their syntax, flow chart, and examples. And at last, we will see a tabular form …

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.

Unlike for loops, while loops work best when the number of iterations isn’t predetermined but depends on dynamic conditions. Structure of a While Loop. The structure of a while loop starts with the keyword while, followed by a condition in parentheses. If the condition evaluates to true, the code block within the loop runs.

Use a for loop when you know the number of iterations or need to iterate over a collection. Use a while loop when the iterations depend on a condition that may change dynamically during execution. for loops are often more readable for iterating over collections, as they clearly express the intention of processing each element.

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.

The primary distinction between a for loop and a while loop in Python lies in how they handle iteration and what controls their execution. For Loop : A for loop is typically used when you have a known sequence of items, such as a list, string, or range, and you need to iterate over each element in that sequence.

Mar 20, 2025 · When to use For Loop and While Loop in Python? A for loop is used when the number of iterations is known or when you are required to iterate over a sequence like a list, tuple, string, or range.

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. For loop also provide a concise way of writing the loop structure. A for loop is indeed not necessary.
