Context Managers and Python's with Statement

In this step-by-step tutorial, you'll learn what the Python with statement is and how to use it with existing context managers. You'll also learn how to create your own context managers.

To summarize what you’ve learned so far, here’s an inexhaustive list of the general benefits of using the Python with statement in your code:

• Makes resource management safer than its equivalent try … finally statements
• Encapsulates standard uses of try … finally statements in context managers
• Allows reusing the code that automatically manages the setup and teardown phases of a given operation
• Helps avoid resource leaks

Using the with statement consistently can improve the general quality of your code and make it safer by preventing resource leak problems.
