Control Flow

With Statement in Python

Used to execute code with an unmanaged resource that may raise an exception. The with statement manages the resource, using it if successful and removing it when the block finishes executing.

Syntax

with resource as resource_var_name:
    #do something with resource

Notes

An example of a resource that may raise an exception is a file stream.

Example

with open('input.txt', 'r') as f:
    data = f.read()
