A simple python script that I created when I had jury duty (Texas) and had to check daily to see if I need to report in.

TexasJuryDuty.py

import cookielib
import socket
import urllib
import urllib2
#r requires BeautifulSoup4
from bs4 import BeautifulSoup

#your jury summons info
participant_number = "#########"
zip_code = "#####"

# jury duty url
url = 'https://jury.txs.uscourts.gov/AppearWeb/Default.aspx'

# setup socket connection timeout
timeout = 15
socket.setdefaulttimeout(timeout)

# setup cookie handler
cookie_jar = cookielib.LWPCookieJar()
cookie = urllib2.HTTPCookieProcessor(cookie_jar)

# create an urllib2 opener()
opener = urllib2.build_opener(cookie)

# build the header for the GET request
http_header = {
                "Host": "jury.txs.uscourts.gov",
                "Connection": "keep-alive",
                "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",

                }

# create the GET request
req = urllib2.Request(url, None, http_header)

# submit the GET request
res = opener.open(req)

# read the response
html = res.read()

#use BS4 to parse html
soup = BeautifulSoup(html, "html.parser")

# get the hidden form elements that we have to include to be a valid site visitor
viewstate = soup.find("input", {"id" : "__VIEWSTATE"})["value"];
viewstategen = soup.find("input", {"id" : "__VIEWSTATEGENERATOR"})["value"];
eventval = soup.find("input", {"id" : "__EVENTVALIDATION"})["value"];

# build the POST request header
