Change double quotes to single quotes, but with a twist - 214 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.
