proxy server for https requests

[tcsmaster]

Hi there!
I would like to use the API but in my organization I can only access the internet via a proxy server.
Maybe this is a dumb question, but is there an easy way for me to include my https_proxy somewhere, in a variable? Looking at the source code, this doesn't seem to be that easy. I'm using Python btw.

Second question: If I wanted to use the requests library, how can I authenticate myself there? There I could use my proxies more easily.

Thanks
