Running Selenium Webdriver with a proxy in Python

I am trying to run a Selenium Webdriver script in Python to do some basic tasks. I can get the robot to function perfectly when running it through the Selenium IDE inteface (ie: when simply getting the GUI to repeat my actions). However when I export the code as a Python script and try to execute it from the command line, the Firefox browser will open but cannot ever access the starting URL (an error is returned to command line and the program stops). This is happening me regardless of what website etc I am trying to access.

I have included a very basic code here for demonstration purposes. I don't think that I have included the proxy section of the code correctly as the error being returned seems to be generated by the proxy.

Any help would be hugely appreciated.

The below code is simply meant to open www.google.ie and search for the word "selenium". For me it opens a blank firefox browser and stops.

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import Select
from selenium.common.exceptions import NoSuchElementException
import unittest, time, re
from selenium.webdriver.common.proxy import *

class Testrobot2(unittest.TestCase):
    def setUp(self):

        myProxy = "http://149.215.113.110:70"

        proxy = Proxy({
        'proxyType': ProxyType.MANUAL,
        'httpProxy': myProxy,
        'ftpProxy': myProxy,
        'sslProxy': myProxy,
        'noProxy':''})

        self.driver = webdriver.Firefox(proxy=proxy)
        self.driver.implicitly_wait(30)
        self.base_url = "https://www.google.ie/"
        self.verificationErrors = []
        self.accept_next_alert = True

    def test_robot2(self):
        driver = self.driver
        driver.get(self.base_url + "/#gs_rn=17&gs_ri=psy-ab&suggest=p&cp=6&gs_id=ix&xhr=t&q=selenium&es_nrs=true&pf=p&output=search&sclient=psy-ab&oq=seleni&gs_l=&pbx=1&bav=on.2,or.r_qf.&bvm=bv.47883778,d.ZGU&fp=7c0d9024de9ac6ab&biw=592&bih=665")
        driver.find_element_by_id("gbqfq").clear()
        driver.find_element_by_id("gbqfq").send_keys("selenium")

    def is_element_present(self, how, what):
        try: self.driver.find_element(by=how, value=what)
        except NoSuchElementException, e: return False
        return True

    def is_alert_present(self):
        try: self.driver.switch_to_alert()
        except NoAlertPresentException, e: return False
        return True

    def close_alert_and_get_its_text(self):
        try:
            alert = self.driver.switch_to_alert()
            alert_text = alert.text
            if self.accept_next_alert:
                alert.accept()
            else:
                alert.dismiss()
            return alert_text
        finally: self.accept_next_alert = True

    def tearDown(self):
        self.driver.quit()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

Works for me this way (similar to @Amey and @user4642224 code, but shorter a bit):

from selenium import webdriver
from selenium.webdriver.common.proxy import Proxy, ProxyType

prox = Proxy()
prox.proxy_type = ProxyType.MANUAL
prox.http_proxy = "ip_addr:port"
prox.socks_proxy = "ip_addr:port"
prox.ssl_proxy = "ip_addr:port"

capabilities = webdriver.DesiredCapabilities.CHROME
prox.add_to_capabilities(capabilities)

driver = webdriver.Chrome(desired_capabilities=capabilities)

How about something like this

PROXY = "149.215.113.110:70"

webdriver.DesiredCapabilities.FIREFOX['proxy'] = {
    "httpProxy":PROXY,
    "ftpProxy":PROXY,
    "sslProxy":PROXY,
    "noProxy":None,
    "proxyType":"MANUAL",
    "class":"org.openqa.selenium.Proxy",
    "autodetect":False
}

# you have to use remote, otherwise you'll have to code it yourself in python to 
driver = webdriver.Remote("http://localhost:4444/wd/hub", webdriver.DesiredCapabilities.FIREFOX)
