Hello,
URLError exception does not highlights unlike others like IOError
Open the Python.tmLanguage file and find this section:
<dict>
<key>builtin_exceptions</key>
<dict>
<key>match</key>
<string>(?x)\b(
(
Arithmetic|Assertion|Attribute|Buffer|EOF|Environment|FloatingPoint|IO|
Import|Indentation|Index|Key|Lookup|Memory|Name|NotImplemented|OS|Overflow|
Reference|Runtime|Standard|Syntax|System|Tab|Type|UnboundLocal|

)Error|
((Pending)?Deprecation|Runtime|Syntax|User|Future|Import|Unicode|Bytes)?Warning|

)\b</string>
Amend to the following (carefully!). Save the file and re-start ST:
|URL|Value|VMS|Windows|ZeroDivision
Thank you! Definitely love this program. It has to have a file monitor cause I did not need to restart it.
