How to use a Proxy with Youtube API? (Python)

I'm working a script that will upload videos to YouTube with different accounts. Is there a way to use HTTPS or SOCKS proxies to开发者_运维技巧 filter all the requests. My client doesn't want to leave any footprints for Google. The only way I found was to set the proxy environment variable beforehand but this seems cumbersome. Is there some way I'm missing? Thanks :)

Setting an environment variable (e.g. import os; os.environ['BLAH']='BLUH' once at the start of your program "seems cumbersome"?! What does count as "non-cumbersome" for you, pray?
