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.

Simple Example to understand Context Manager

Let’s talk about some real-world use cases for context managers in Python.

  1. File Handling: When working with files, a context manager ensures that the file…
