Loops are fundamental programming structures that allow repetitive execution of a block of code while certain conditions are met. They are incredibly useful for tasks that require the same action or a similar set of actions to be performed multiple times, which is a common scenario in programming. Python provides several loop constructs that enable these repetitive actions to be handled in an efficient, readable, and concise manner.

Types of Loops and Control Statements

1. for Loop: Used for iterating over a sequence (such as a list, tuple, string) or other iterable objects. Iterating over a sequence is called traversal.

2. while Loop: Repeats as long as a certain boolean condition is met. It is useful when the number of iterations is not known before the first iteration begins.

3. Loop Control Statements: Modify the behavior of the loop from its normal sequence. These are:

   • break: Exits the loop immediately, skipping the remainder of its body and any remaining iterations.
   • continue: Skips the rest of the loop's body for the current iteration and moves on to the next iteration of the loop.
   • pass: Acts as a placeholder; it does nothing and is used when a statement is required syntactically but no action needs to be performed.

Loops can significantly reduce the amount of code required in a program by handling repetitive tasks automatically while making the code easier to read and maintain. They are a powerful tool in data processing, automating tasks, and more. Understanding how to use loops efficiently is a crucial skill in programming.

In the following lessons, we will dive deeper into each type of loop and control statement, exploring their syntaxes, use cases, and best practices. Let's start with the for loop in Python.
