Here's the equivalent in pycurl:
import pycurl
from StringIO import StringIO
response_buffer = StringIO()
curl = pycurl.Curl()
curl.setopt(curl.URL, "http://api.foursquare.com/v1/venue.json?vid=2393749")
curl.setopt(curl.USERPWD, '%s:%s' % ('youruser', 'yourpassword'))
curl.setopt(curl.WRITEFUNCTION, response_buffer.write)
curl.perform()
curl.close()
response_value = response_buffer.getvalue()

"The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.
Try using headers to do authentication:"
taked from Python urllib2 Basic Auth Problem
import urllib2
import base64
req = urllib2.Request('http://api.foursquare.com/v1/venue.json?vid=%s' % self.venue_id)
req.add_header('Authorization: Basic ',base64.b64encode('email:password'))
res = urllib2.urlopen(req)

I'm more comfortable running the command line curl through subprocess. This avoids all of the potential version matching headaches of python, pycurl, and libcurl. The observation that pycurl hasn't been touched in 2 years, and is only listed as suppported through Python 2.5, made me wary. -- John
import subprocess
def curl(*args):
curl_path = '/usr/bin/curl'
curl_list = [curl_path]
for arg in args:
curl_list.append(arg)
curl_result = subprocess.Popen(
curl_list,
stderr=subprocess.PIPE,
stdout=subprocess.PIPE).communicate()[0]
return curl_result
answer = curl('-u', 'email:password', 'http://api.foursquare.com/v1/venue.json?vid=2393749')

if use human_curl you can write some code
import human_curl as hurl
r = hurl.get('http://api.foursquare.com/v1/venue.json?vid=2393749', auth=('email','password'))
Json data in r.content

Use pycurl
There is a discussion on SO for tutorials
A typical example:
import sys
import pycurl
class ContentCallback:
def __init__(self):
self.contents = ''
def content_callback(self, buf):
self.contents = self.contents + buf
t = ContentCallback()
curlObj = pycurl.Curl()
curlObj.setopt(curlObj.URL, 'http://www.google.com')
curlObj.setopt(curlObj.WRITEFUNCTION, t.content_callback)
curlObj.perform()
curlObj.close()
print t.contents

You can use
pycurl, but it's not required. It's quite possible to use the standard library. See the question I linked above.
