In Python, a sufficiently recent httplib2 will require valid certificates by default; same with the requests library. Both let you use your own cert bundle, as a quick-and-dirty way to do certificate pinning. That's reason enough to discourage the use of Python's standard library for http requests (another reason is that it's quite low-level).
