Pyhon Loop statements

Loops are a fundamental concept in Python that allow you to execute a block of code repeatedly. Python supports two types of loops: for loops and while loops. Here's a detailed overview of how to use loops in Python:

1. for Loops

The for loop in Python is used to iterate over a sequence (such as a list, tuple, dictionary, set, or string).

Basic for Loop

Iterating Over a String

Using range()

The range() function generates a sequence of numbers, which is useful for creating loops with a specific number of iterations.

Using range() with Start, Stop, and Step

2. while Loops

The while loop executes as long as a specified condition is true.

Basic while Loop

3. Control Statements in Loops

break Statement

The break statement is used to exit the loop prematurely when a certain condition is met.

continue Statement

The continue statement skips the current iteration and moves to the next iteration of the loop

else Clause with Loops

The else clause in a loop executes after the loop completes normally (i.e., not terminated by break).

Summary

• for loop: Used for iterating over a sequence (list, string, etc.).
• while loop: Repeats as long as a condition is true.
• break statement: Exits the loop prematurely.
• continue statement: Skips the current iteration.
• else clause with loops: Executes after the loop completes normally.

Loops are essential for tasks that require repetitive execution of code, and mastering them will significantly enhance your ability to write efficient and effective Python programs.
