What is a For Loop?
The for loop in Python is used for iterating over a sequence of elements, like items in a list, characters in a string, or numbers in a range. Instead of repeatedly writing code to handle each element, the loop lets you write instructions once and applies them to each item in the sequence.

How For Loops Work in Python
Initialization: When the loop begins, Python identifies the collection of elements (such as a list or range).
Iteration: The loop goes through each item in the collection, one at a time. For each item, Python temporarily stores it in a variable.
Execution: For each element, Python performs the actions defined in the loop's body.
Completion: The loop stops after reaching the end of the collection.
Where For Loops are Used
Lists: To access or modify each item in a list.
Strings: To process each character in a string individually.
Dictionaries: To go through each key-value pair.
Ranges: To generate a series of numbers within a specified range.
Key Features of Python’s For Loop
Readable Syntax: The Python for loop has a straightforward syntax that is beginner-friendly.
Dynamic Collections: It works seamlessly with various data types, including lists, strings, dictionaries, and even custom collections.
Unmatched Flexibility: Using the loop, you can modify or filter data, perform calculations, or execute other actions based on each item.
Loop Control
Python provides options to control the flow within a loop:

Break: Immediately exit the loop.
Continue: Skip the current iteration and move to the next.
Else with For Loops: Python allows an else clause to run if the loop completes without interruptions, adding a unique layer of control.
Summary
The for loop in Python is a core tool for efficiently managing and processing collections. Its simplicity and adaptability make it essential for data manipulation, automation, and much more.
