Description updated, upvote for clarity in issue raising.

Test cases are indeed not sufficient in Python

I've updated the Python version to also have singular nouns. Thanks -

Many thanks for the translation!

7 * 52 days is not 1 year... see my comment below.

Approved

Thanks!

Can't agree more with your point of view, bravo :)!

Yeah, its difficult to specify this without either supplying a range for each of the limits, or allowing that the one with the largest number applies as soon as the previous one is exceeded.

I've added something to the description as a warning.

No worries. Thanks for the input anyway. And thanks a lot for the C# translation! :)

Added a clarification to the beginning of the note.

Thanks for your comment @LazyWolf. Please take another look at the description. The examples in the note at the bottom of the description are there purely to address the fact that spoonerisms CAN be more complicated than two words, but it clearly states that you will NOT have to account for these more complex forms in your code. Even so, I will edit the description to try and make this more clear. :)

Thank you for you time and interest :)

Thank you for sharing your idea. I added the mentioned test cases.
And I guess your code won't pass now.
