I am trying to use Python to login to a website and gather information from several webpages and I get the following error:

Traceback (most recent call last):
  File "extract_test.py", line 43, in <module>
    response=br.open(v)
  File "/usr/local/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 203, in open
    return self._mech_open(url, data, timeout=timeout)
  File "/usr/local/lib/python2.7/dist-packages/mechanize/_mechanize.py", line 255, in _mech_open
    raise response
mechanize._response.httperror_seek_wrapper: HTTP Error 429: Unknown Response Code

I used time.sleep() and it works, but it seems unintelligent and unreliable, is there any other way to dodge this error?

Here"s my code:

import mechanize
import cookielib
import re
first=("example.com/page1")
second=("example.com/page2")
third=("example.com/page3")
fourth=("example.com/page4")
## I have seven URL"s I want to open

urls_list=[first,second,third,fourth]

br = mechanize.Browser()
# Cookie Jar
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)

# Browser options 
br.set_handle_equiv(True)
br.set_handle_redirect(True)
br.set_handle_referer(True)
br.set_handle_robots(False)

# Log in credentials
br.open("example.com")
br.select_form(nr=0)
br["username"] = "username"
br["password"] = "password"
br.submit()

for url in urls_list:
        br.open(url)
        print re.findall("Some String")
