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 …

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.

Dec 10, 2024 · This code uses a for loop to iterate over a string and print each character on a new line. The loop assigns each character to the variable i and continues until all characters in the string have been processed.

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.

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.

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.

Mar 10, 2025 · Learn to write Python for loops with statements like break and continue to iterate through lists to clean and analyze large datasets quickly.

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.

Jan 24, 2025 · 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 the for loop syntax is essential for writing efficient and concise Python code.

Mar 14, 2019 · In Python we have three types of loops for, while and do-while. In this guide, we will learn for loop and the other two loops are covered in the separate tutorials. Here <variable> is a variable that is used for iterating over a <sequence>. On every iteration it takes the next value from <sequence> until the end of sequence is reached.
