Change double quotes to single quotes, but with a twist - 142 entries

Although this challenge is in the context of a Python function, you don't need to know Python to do this challenge. It is to add contexts and interesting constraints. The file contains a function that prints a multi-line string literal. I wrote the string literal with double quotes, but then I decided to use single quotes instead, and that's your challenge. However, interestingly enough, the string itself contains single and double quotes. This means, inside the string literal, the originally escaped double quotes no longer need to be escaped, but the single quotes now need to be escaped. Note that the triple double quotes in the docstring should be left alone.

Unsemantic linewrapping - 738 entries

[Inspired by a blog post I read: https://scott.mn/2014/02/21/semantic_linewrapping/. Text adapted.] Sometimes when editing a Markdown file, I wrap the lines semantically. Instead of inserting a newline at 70 columns (or whatever), or making paragraphs one long line, I put in newlines at a point that seems logical to me. This may seem silly, but it produces better diffs. Semantic linewrapping also makes editing snappier. I can delete, edit or insert sentences easily using linewise operations. Code-oriented text editors like Vim and [REDACTED] are really good at this kind of manipulation. Editing text that hasn't been wrapped semantically is a pain, though:
