Python For Loops. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string). This is less like the for keyword in other programming languages, and works more like an iterator method as found in …

Mar 8, 2025 · In this article, we will look at Python loops and understand their working with the help of examples. In Python, a while loop is used to execute a block of statements repeatedly until a given condition is satisfied. When the condition becomes false, the line immediately after the loop in the program is executed.

Loops are constructs that repeatedly execute a piece of code based on the conditions. See various types of loops in Python with examples.

In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it.

Python’s for loop allows you to iterate over the items in a collection, such as lists, tuples, strings, and dictionaries. The for loop syntax declares a loop variable that takes each item from the collection in each iteration. This loop is ideal for repeatedly executing a block of code on each item in the collection.

Sep 18, 2023 · In this article, we looked at how to use Python loops to execute a piece of code repeatedly. Understanding how Python’s for and while loops work is fundamental to programming, since you’ll be using them all the time.

Jul 27, 2021 · What is a for loop in Python? A for loop can iterate over every item in a list or go through every single character in a string and won't stop until it has gone through every character. Writing for loops helps reduce repetitiveness in your code, following the DRY (Don't Repeat Yourself) principle.

In Python, a for loop can be used to perform an action a specific number of times in a row. The range() function can be used to create a list that can be used to specify the number of iterations in a for loop. An infinite loop is a loop that never terminates. Infinite loops result when the conditions of the loop prevent it from terminating.

Mar 10, 2025 · To create a Python for loop, you start by defining an iteration variable and the iterable object you want to loop through. The iteration variable temporarily holds each item from the iterable during each loop. Then, inside the loop, you specify the actions you want to perform using this variable.

Feb 24, 2025 · One important feature of Python is loops. A loop lets you run the same code many times without writing it again. Loops help your program repeat actions, like: Using loops saves time, reduces mistakes, and makes your code more …
