What exactly do you mean by "make an https client"?

What OS are you on?

Are you sure it's NOT compiled in?  But, if it's not compiled, it's
not compiled.

Since you say "make a certificate", and mention "https client", it
sounds like you want to authenticate yourself to an HTTP server using
an SSL certificate?  If so, I don't believe the issue Benji raised is
relevant (that issue is relevant for fetching HTTPS URLs rather than
authenticating yourself to a server using an SSL certificate, I
think).

urllib claims to have support for this in the form of the key_file and
cert_file arguments to Urlopener constructor (UNTESTED):

import urllib
opener = urllib.URLopener(key_file="/path/to/my_key_file",
                          cert_file="/path/to/my_cert_file")
response = opener.open(url)


I can't claim to know that it actually works, though...
