Context Manager in Python
In Python, “context manager” usually refers to the context in which a piece of code is executed. One common use is the “context manager,” which is a way of managing resources, such as files or network connections, efficiently.
A context manager is created using the with
statement. It ensures that setup code is run before the block of code inside the with
statement is executed, and teardown code is run afterwards. This helps in resource management and makes the code cleaner.
Let’s understand with the simple analogy
Imagine you have a magic box (let’s call it a context manager) that helps you with a task. When you want to use the magic box, you say, “Hey, magic box, do your thing!” When you’re done, you say, “Okay, magic box, I’m done now.”
So, “context manager” in Python often means using this nice structure (the with
statement) to manage tasks neatly. It's like having a helper (context manager) that knows when to start and when to stop doing something.
Let’s talk about some real-world use cases for context managers in Python.
