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.

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":

To get a clear idea about how a for loop works, I have provided 21 examples of using for loop in Python. You can go through these examples and understand the working of for loops in different scenarios. Let’s dive right in. 1. Python for loop to iterate through the letters in a word. print(i) 2. Python for loop using the range () function. print(j)

Dec 10, 2024 · Python For Loops are used for iterating over a sequence like lists, tuples, strings, and ranges. For loop allows you to apply the same operation to every item within loop. Using For Loop avoid the need of manually managing the index. For loop can iterate over any iterable object, such as dictionary, list or any custom iterators. For Loop Example:

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.

Apr 19, 2025 · for loop: Iterate over a sequence of elements such as a list or string. range () function: Using a for loop with range (), we can repeat an action a specific number of times. while loop: To execute a code block repeatedly, as long as the condition is True. Break and Continue: To alter the loop’s execution in a particular manner.

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.

Python’s for loop iterates over items in a data collection, allowing you to execute code for each item. To iterate from 0 to 10, you use the for index in range(11): construct. To repeat code a number of times without processing the data of an iterable, use the …

Jul 27, 2021 · Loops let you control the logic and flow structures of your programs. Specifically, a for loop lets you execute a block of similar code operations, over and over again, until a condition is met. You repeat certain code instructions for a set of values you determine, and you perform actions on each value for a pre-determined number of times.

6 days ago · 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 …
