Removed unnecessary line from `tag.parent` example

[r4j4h]

Summary

I removed a line from a tag.parent example because as far as I can tell it did not need to be there and did not contribute to the example but instead served to distract from it. :)

Proposed changes:

• One line is removed from the tag.parent example

Resolves no existing issue, but hopefully resolves potential distractions from readers.

Agreed. Line doesn't need to be there and just causes confusion. Will merge. Thank you!
