API request stopped working, can someone help?

I used the code below to pull my games archives but it stopped working recently.  I'm not very literate so I can't tell whether it's something with the Python library or the chess.com API.  This is part of the error message I get:

Traceback (most recent call last):
File "C:/Users/Bob/Desktop/chess.py", line 9, in <module>
f = urllib.request.urlopen(archivesUrl)
File "C:\Users\Bob\AppData\Local\Programs\Python\Python37-32\lib\urllib\request.py", line 222, in urlopen
return opener.open(url, data, timeout)

Here is the code I was using:

import urllib
import urllib.request

username = "BobChess" #change
baseUrl = "https://api.chess.com/pub/player/" + username + "/games/"
archivesUrl = baseUrl + "archives"

#read the archives url and store in a list
f = urllib.request.urlopen(archivesUrl)
archives = f.read().decode("utf-8")
archives = archives.replace("{\"archives\":[\"", "\",\"")
archivesList = archives.split("\",\"" + baseUrl)
archivesList[len(archivesList)-1] = archivesList[len(archivesList)-1].rstrip("\"]}")

#download all the archives
#indent all lines below except first and last ones
for i in range(len(archivesList)-1):
url = baseUrl + archivesList[i+1] + "/pgn"
filename = archivesList[i+1].replace("/", "-")
urllib.request.urlretrieve(url, "C:/Users/Bob/Desktop/Chess/" + filename + ".pgn") #change
print(filename + ".pgn has been downloaded.")
print ("All files have been downloaded.")

name error?

Stack trace? Also is this using Django, Flask? From where are you calling this? 

Is data sourcing from chess.com possible? 

Just from a copy of Python on my laptop.  Python 3.7 32-bit if that helps?

This is so rude!

archives = archives.replace("{\"archives\":[\"", "\",\"")
archivesList = archives.split("\",\"" + baseUrl)
archivesList[len(archivesList)-1] = archivesList[len(archivesList)-1].rstrip("\"]}")

You are working with the endpoint like with a string, but have you ever heard that API returns JSON? Using JSON module, you can easily convert response into Python classic types. Check it here ( https://docs.python.org/3.5/library/json.html ).

And many other things that make shivers run over the skin... Nevertheless, the answer on your question: with this code you should always use username lower-cased. I. e. username = "bobchess" etc.

Did you copy this code from somewhere?

xtxoxpxd, did you manage to sort out your problem?
