With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. Print each fruit in a fruit list: The for loop does not require an indexing variable to set beforehand. Even strings are iterable objects, they contain a sequence of characters: Loop through the letters in the word "banana":

In Python, we use a for loop to iterate over sequences such as lists, strings, dictionaries, etc. For example, # access elements of the list one by one for lang in languages: print(lang) Output. In the above example, we have created a list named languages. Since the list has three elements, the loop iterates 3 times. The value of lang is.

Python For Loop can be used to iterate a set of statements once for each item of a sequence or collection. The sequence or collection could be Range, List, Tuple, Dictionary, Set or a String. In this tutorial, we will learn how to implement for loop for each of the above said collections.

Dec 10, 2024 · In Python, enumerate () function is used with the for loop to iterate over an iterable while also keeping track of index of each item. This code uses nested for loops to iterate over two ranges of numbers (1 to 3 inclusive) and prints the value of i and j …

In Python programming, we use for loops to repeat some code a certain number of times. It allows us to execute a statement or a group of statements multiple times by reducing the burden of writing several lines of code. To get a clear idea about how a for loop works, I have provided 21 examples of using for loop in Python.

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 this article, we will learn different types of loops in Python and discuss each of them in detail with examples. So let us begin. In programming, the loops are the constructs that repeatedly execute a piece of code based on the conditions.

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.

Jan 7, 2024 · In this example we will use for loop to iterate over the individual values of list. We declare a variable called numbers and initialize numbers to a list of integers from 1 to 5. next loop through this list and inside the loop calculate the square of num by multiplying it by itself. Output from this script: 1 squared is 1.

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.
