How do I pass username and password in basic authentication?

How to pass username and password in HTTP request?

I have a web service where I need to get some info from it.

The web service is returning me some data using GET method. I can easily do this.

But now I want to pass username and password in request. I know that the username and password should be encoded in url request. But how can I do it? Is there any way to get it working? Can anybody help me with this? You can use the urllib.HTTPBasicAuthHandler for this purpose. The password is in the form "username:password". So just replace the "username" part with your username and the "password" part with your password.
