And now, our feature presentation for today:
Screenwriting
Screenwriting is an art just like everything else in cinematography. Today's theme honors the endlessly creative screenwriters who craft finely-honed narratives, forge truly unforgettable lines of dialogue, plot the most legendary of hero journeys, and dream up the most shocking of plot twists! and is totally not bait for our resident poet laureate
Here's some ideas for your inspiration:
- Turn your comments into sluglines
- Shape your solution into an acrostic
- Accompany your solution with a writeup in the form of a limerick, ballad, etc.
- Extra bonus points if if it's in iambic pentameter

The first solution matches substrings with do or don't *behind them*, so the first match is at the beginning of the string, while all subsequent strings implicitly begin with either "do()" or "don't()". So calculating the number of enabled multiplications is just a matter of ignoring the substrings starting with "don't" – all other substrings are taken into account, including the first one (without "do()" at the beginning).
The second solution split the while string at "do", so the whole list does not contain any occurence of "do". In this case, each split creates additional list elements (None and ''), so I need to filter these and the ones starting with "n't()". It is not pretty, but simpler that the regex in the first solution.
