Scary but interesting question, thanks Grant. At first I thought that all possible answers could be considered correct. After a moment of despair, I found a hint for the right...

Great question, thanks John. Some typo doesn't matter, and the same two answers don't. After all, one correct answer rules out the remaining... Thanks also to Carlo Romagnano for clarifying...

Thanks Steve for this interesting question. I'm surprised how cute Python is, he doesn't mind square brackets in the right answer ... 🙂

Ah..., my apologies, it is obvious that in the expression '1.77 + 0. test' is the second dot also an decimal point. I had to be blind. I have overlooked...
