1. flake8.
2. Duplicate tests.

[jaykay12]

Okay! Let me check for flake8 😊
But I am unable to understand what you mean by duplicate tests? The 2nd test I added differs in the regex pattern from all the first one.

[dstftw]

It tests the same extraction scenario.

[jaykay12]

Yeahh I does. So, what should I do now?
Should I remove the test I added?
I thought it will be cool to have a new test for such a new sort of url & wasn't aware about the fact that all tests should follow atleast different extraction methods. apologies. 😞

[dstftw]

Make them only matching.
