How to write a selenium loop in Python?

I want to web-scrape data from many different websites which contains javascript code (thus why I am using the selenium method to get the information). Everything is working great, but when I try to load the next URL I get a very long error message :

> Traceback (most recent call last):
  File "C:/Python27/air17.py", line 46, in <module>
    scrape(urls)
  File "C:/Python27/air17.py", line 28, in scrape
    browser.get(url)
  File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 268, in get
    self.execute(Command.GET, {'url': url})
  File "C:\Python27\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 254, in execute
    response = self.command_executor.execute(driver_command, params)

    return self._request(command_info[0], url, body=data)
  File "C:\Python27\lib\site-packages\selenium\webdriver\remote\remote_connection.py", line 487, in _request

    self.endheaders(body)

    self.connect()
  File "C:\Python27\lib\httplib.py", line 821, in connect
    self.timeout, self.source_address)
  File "C:\Python27\lib\socket.py", line 575, in create_connection
    raise err
error: [Errno 10061] 

The data from the first website is in the csv file, but when the code tries to open the next website it freezes, and I get this error message. What am I doing wrong?

            datatable.append(temp_data)

        output.writerows(datatable)

        resultcsv.close()
        time.sleep(10) 
        browser.quit()

urls = ["https://www.flightradar24.com/data/airports/bud/arrivals", "https://www.flightradar24.com/data/airports/fco/arrivals"]
scrape(urls)
