Nitty-gritty of “with” statement in Python
This article lets you delve into the world of Python’s with statement and explore its significance, use cases, and practical applications. So, let’s get started.
Introduction
You know that the try ... except ... finally construct is used for exception handling as well as cleaning some resources such as closing a file.
In Python, the with statement is a concise shorthand that replaces a try … except …finally block. It is used for resource management and exception handling. Importantly, it ensures that resources are closed immediately after processing.
The with statement revolutionizes the management of shared resources like file streams, efficiently guaranteeing that resources are meticulously cleaned up after use, irrespective of whether an exception arises, through the execution of a block of code.
A common example of using the with statement is reading or writing to a file.
The with statement helps you implement some common resource management patterns by abstracting their functionality and allowing them to be factored out and reused.
