What does the for loop do in Python?

• A. Iterates through a sequence.
• B. Checks for a true condition.
• C. Runs indefinitely.
• D. Stops a loop abruptly.

Answer: (A)

The for loop in Python is designed specifically to iterate through a sequence, which can include lists, tuples, strings, or any other iterable object. When a for loop is initiated, it takes each element from the sequence one at a time and executes the contained block of code for that particular element. This allows for efficient processing of data, enabling programmers to easily repeat actions for each item within a collection.

For instance, if you have a list of numbers and you wish to print each number, a for loop facilitates this by automatically traversing the list and performing the print operation for each value without the need for manual indexing or counting. This structured and readable approach significantly simplifies code development and enhances maintainability.
