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":

There are two types of loops in Python and these are for and while loops. Both of them work by following the below steps: 1. Check the condition. 2. If True, execute the body of the block under it. And update the iterator/ the value on which the condition is checked. 3. …

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.

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.

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, 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.

Oct 30, 2020 · In this article, We are going to cover Loops in Python with Examples, Break Statement in Python, Continue Statement in Python, Pass Statement in Python, range () function in Python, for-else loop in Python. In simple language for loop is a programming language statement which allows code to be repeatedly executed.

Apr 25, 2025 · Using for Loop with range() The Python range() built-in function generates a sequence of integers, often used with for loops. print(i) Output: You can also specify a start, stop, and step value. Open up your own Python editor to see for yourself: print(i) Output: Iterating Over a String. print(char) Output: Looping Through a Dictionary.

Apr 23, 2025 · Looping is a fundamental concept in programming that allows you to execute a block of code multiple times. In Python, the `for` loop is a powerful and versatile tool for iterating over sequences (such as lists, tuples, strings) or other iterable objects. Understanding how to use the `for` loop effectively can greatly simplify your code and make it more efficient. This blog post will dive deep ...
