Werkzeug is a WSGI utility library for Python. It’s widely used and BSD licensed.

Werkzeug is Simple

from werkzeug.wrappers import Request, Response

def application(request):
    return Response('Hello World!')

if __name__ == '__main__':
    from werkzeug.serving import run_simple
    run_simple('localhost', 4000, application)

And Powerful

Werkzeug started as a simple collection of various utilities for WSGI applications and has become one of the most advanced WSGI utility modules. It includes a powerful debugger, fully featured request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a powerful URL routing system and a bunch of community contributed addon modules.

It does Unicode and doesn’t enforce a specific template engine, database adapter or anything else. It doesn’t even enforce a specific way of handling requests and leaves all that up to the developer.
