Python HTTP for Humans.
Requests is an ISC Licensed HTTP library, written in Python, for human beings.
Most existing Python modules for sending HTTP requests are extremely verbose and cumbersome. Python’s builtin urllib2 module provides most of the HTTP capabilities you should need, but the api is thoroughly broken. It requires an enormous amount of work (even method overrides) to perform the simplest of tasks.
Things shouldn’t be this way. Not in Python.
>>> r = requests.get('https://api.github.com', auth=('user', 'pass')) >>> r.status_code 204 >>> r.headers['content-type'] 'application/json' >>> r.text ...
See the same code, without Requests.
Requests allow you to send HEAD, GET, POST, PUT, PATCH, and DELETE HTTP requests. You can add headers, form data, multipart files, and parameters with simple Python dictionaries, and access the response data in the same way. It’s powered by httplib and urllib3, but it does all the hard work and crazy hacks for you.

Sessions with Cookie Persistence
Browser-style SSL Verification
Elegant Key/Value Cookies
Unicode Response Bodies
Multipart File Uploads
To install requests, simply:
$ pip install requests
Or, if you absolutely must:
$ easy_install requests
But, you really shouldn’t do that.
Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug. There is a Contributor Friendly tag for issues that should be ideal for people who are not very familiar with the codebase yet.
Fork the repository on Github to start making your changes to the develop branch (or branch off of it).
Write a test which shows that the bug was fixed or that the feature works as expected.
Send a pull request and bug the maintainer until it gets merged and published. :) Make sure to add yourself to AUTHORS.
