The For Loop in Python

Python offers several constructs to handle repetitive tasks efficiently. One such very important and must-know construct is the 'for' loop.

In this module, we will explore the 'for' loop in Python, its syntax, implementation, and discuss some code examples to illustrate its functionality.

Whether you're a beginner or an experienced programmer, understanding the 'for' loop will undoubtedly enhance your ability to write clean and concise code.

What is a For Loop?

A 'for' loop is a control flow statement that allows you to iterate over a sequence of elements. It executes a block of code repeatedly, once for each item in the sequence, until all the elements have been processed.

The 'for' loop is particularly useful when you know the number of iterations in advance or when you need to iterate over a fixed-length sequence, such as a list or a string.

Syntax: The basic syntax of a 'for' loop in Python is as follows:

 >>> for item in sequence:
 >>>      # Code block to be executed

The 'item' represents the current element in the sequence, and 'sequence' refers to the iterable object over which the loop iterates.

The code block , indented below the 'for' statement, defines the actions to be performed for each item in the sequence.
