How do I disable the security certificate check in Python's Requests?

I am using

import requestsrequests.post(url='https://foo.example', data={'bar':'baz'})

but I get a request.exceptions.SSLError.

The website has an expired certificate, but I am not sending sensitive data, so it doesn't matter to me.

I would imagine there is an argument like 'verifiy=False' that I could use, but I can't seem to find it.
