Python 3.8 urllib issue

[1995parham]

In python 3.8 the following code:

urllib.request.urlopen('file:///home/parham/.bashrc')

Generates the following error:

Traceback (most recent call last):

And this cause issue with validator when it tries to fetch a local schema file.

Hi. Seems to work fine here:

⊙  python3.8 -c 'import urllib.request; print(urllib.request.urlopen("file:///dev/zero").read(2))'                                                                                              julian@Air ●
b'\x00\x00'

You'd have to be more specific. py3.8 didn't change anything about urlopen as far as I know.

Thanks for your quick response. I am using getting here because of this issue.
I am getting an error with your given code too. I am using python 3.8.5 that is installed with brew. Yes, I am checking the urllib code too, and cannot find anything that is changed recently.
