I am trying to find out if a set of urls exist or if they will give back an error without having to go through all of them. I am using python 3.5.0. The basic URl is http://www5.registraduria.gov.co/CuentasClarasPublicoCon2014/Consultas/Candidato/Reporte/2 and it changes by adding a simple number at the end (from 0 to at most 10000). I tried the following:
import requests, os, bs4
url = 'http://www5.registraduria.gov.co/CuentasClarasPublicoCon2014/Consultas/Candidato/Reporte/'
start = 0 #Start the count,
urllook = url+str(start) #Add the count to the url
res = requests.get(urllook)#Talk to the page
goodid = []#create empty array of candidate id
while start<10000: #It seems like there are no candidates more than 5000, just to be sure made it big
res = requests.get(urllook) #Talk to page again
if res.ok: #If no error
start=start+1 #increase count by one
print(start) #what page I'm at
goodid.append(start) #Add to the goodid array
urllook=url+str(start) #Increase the URL by one
else: #If error then
start=start+1 #Increase count by one
print(start) #what page I'm at
urllook=url+str(start) #Increase the URL by one
print("LOL")
This works for small number of urls, like from 0 to 100 but I want to make sure I have them all. I was hoping to save the goodid object in a .txt file I could access later but it seems to be having an error I can't figure out, at random urls, after some time. This is the error:

It seems like the main problem is that it returns a buffering error, but it does so at different urls, it has happened at /197 in a different run at 273 and the last one at 692. How can solve this error? What does it mean?
Unrelated but if anyone have any suggestions on doing this faster I welcome them, I'm fairly new to python, and not a programming expert in general.
EDIT: I understand now that connection reset by peer means the server closed the connection, but I still don't understand why, specially I don't understand why it is happening at random URLs
