In the world of programming, working with files is a fundamental task that developers often encounter. Python, with its rich standard library, offers an array of tools to handle file operations effectively.

One of the key aspects of file handling is control flow, which allows you to manage the execution of your code based on specific conditions or loops. In this article, we’ll explore how to leverage Python’s control flow statements to perform various file operations with ease.

Reading Files

Reading the contents of a file is a common operation, and Python’s control flow statements can help you navigate through the file’s data efficiently. Here’s an example of how to read a file line by line using a for loop:

with open('file.txt', 'r') as file:
    for line in file:
        print(line.strip())

In this example, the with statement ensures that the file is properly closed after the loop completes, even if an exception occurs. The for loop iterates over each line in the file, and the strip() method removes any leading or trailing whitespace characters.
