You need find a way for add header at request 'urllib.request.urlretrieve', like this: {"User-Agent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0"} ?
Your code should seem like a Webbrowser for OSM servers, not a script.

I'm not sure if it goes against OSM terms and conditions

I made a small example. I try to download the OSM tile in two ways:

• requests.get (without any headers)
• requests.get (with headers)

Only the second method works with OSM.
See code and result below.

Code:

import requests

url = "https://a.tile.openstreetmap.org/1/0/0.png"

print("Try download OSM tile without 'headers'...")
r = requests.get(url)
print(r)
if r.status_code == 200:
	with open("0.png", "wb") as f:  # saves '0.png'
		f.write(r.content)

print("Try download OSM tile with 'headers'...")
r = requests.get(url, headers={"User-Agent": "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0"})
print(r)
if r.status_code == 200:
	with open("0_.png", "wb") as f:  # saves '0_.png'
		f.write(r.content)

Result:

Try download OSM tile without 'headers'...
<Response [429]>
Try download OSM tile with 'headers'...
<Response [200]>

If you change url to another tile server, for example: https://maps.wikimedia.org/osm-intl/1/0/0.png, both download methods are works properly:

Try download OSM tile without 'headers'...
<Response [200]>
Try download OSM tile with 'headers'...
<Response [200]>

OSM server does not allow to download the tile if no headers is specified...

Note that it is against OSM tiles server rules to bulk download tiles like this.
