urllib Connection Pool in Python

When making multiple requests to a web server using Python's urllib module, it's best practice to use a connection pool rather than opening a new connection for every request.

Here's a quick example:

import urllib.request

http = urllib.request.PoolManager()

response1 = http.request('GET', 'http://example.com/')
response2 = http.request('GET', 'http://example.org/') 

This creates a pool manager that reuses connections rather than closing and reopening new ones. Some key benefits:

Behind the scenes, the pool handles the connections for you. When you're done, simply close the pool:

http.clear() 

So in summary, using a connection pool is an easy way to boost efficiency and speed when making multiple requests in urllib. Give it a try next time!
