Python comments are marked for "Sentence does not start with a capital letter"

**What got flagged?**
Python commands like ``# this is where you would insert your policy`` are often flagged for _This sentence does not start with a capital letter_. Here the word "this" is flagged.

**Why is this incorrect?**
It is not a full sentence. Therefore I want to start with a lowercase letter.

**Example of correct usage:**
`` # this is a comment``

Start by reproducing the reported warning with the Python comment example in the issue, then trace the capitalization rule that flags the word "this". Done means lowercase Python comments no longer trigger this warning while ordinary sentences still receive the capitalization check.
