Maybe being blunt, but if you're seriously about to be out of house and home because you can't find a job, you need to lower your fence. Aspiring to be a programmer/hacker/startup guy is great, but even a job stacking shelves in a shop would give you enough money to survive on while you continue looking for a job you'd enjoy (Or working on your own projects). Put it this way, living on the street gives you hardly any chance of getting somewhere you want to be. Having a house and a crappy job for a few years while you get back on your feet is a much better choice.
Agreed (there are many steps between "can't find a job coding python" and homelessness), and to extend this a bit -- if you're panicked about a desperate money situation, it's gotta be hard to concentrate enough to write code worth a damn, or do any other task that requires concentration (including having the presence of mind and confidence to properly network with other hackers in the rare occasion you may see them IRL).
I'd try finding some kind of homeostasis first -- possibly including some kind of job you'll never put on your resume, and cutting living expenses to the bone if you haven't already; and is there any social services support available? -- and once you've stopped the downward slide, it gets easier to think clearly about what to do next.
And as mentioned by others, definitely check out the "hackers wanted" and related topics posted monthly; that's where I got my current gig. But it takes time to get through to where you're actually earning money, even if you start some conversations with interested potential employers -- particularly if you're trying to work remotely! -- so you very likely need to take steps immediately to get things back under control regardless of what options turn up there.
This country is harsh and there is NO safety net for the able bodied at the end of a rope. Deliver pizza (and get shot), stock shelves, what ever it takes.
You are not your job. It is illegal to be homeless in the USA.
