Python script to check HTTP status and redirect chains

Here’s a quick and dirty Python script that goes through a list of URLs, and for each URL checks HTTP status codes (200, 301, 404, etc.), along with number of redirects and redirect chains (each redirect destination).  Saves output into a text file (you can modify to save to CSV, but I used text import feature in Excel to import tab-delimited data).

Well, damn hosted WordPress doesn’t let me paste code correctly, so here’s the link to Gist.

import requests
def get_status_code(url):
r = requests.get(url)
print "Processing " + url
if len(r.history) > 0:
chain = ""
code = r.history[0].status_code
final_url = r.url
for resp in r.history:
chain += resp.url + " | "
return str(code) + '\t' + str(len(r.history)) + '\t' + chain + '\t' + final_url + '\t'
return str(r.status_code) + '\t\t\t\t'
except requests.ConnectionError:
print("Error: failed to connect.")
return '0\t\t\t\t'
input_file = 'urls.txt'
output_file = 'output.txt'
with open(output_file, 'w') as o_file:
o_file.write('URL\tStatus\tNumber of redirects\tRedirect Chain\tFinal URL\t\n')
f = open(input_file, "r")
lines =
for line in lines:
code = get_status_code(line)
o_file.write(line + "\t" + str(code) + "\t\n")

  1. Hey Tanya, awesome script…this still worked for me 5 years on! The only thing I had to change was adding brackets to the print function on line 6. Not sure if that’s a Python2 to Python3 thing as I’m still fairly new to this language, but either way it worked great in the end.

    Thanks for sharing this, it’s really helpful to see and run other people’s code examples :-)
