String not exact?

I cannot believe this idiocy!!!

I stared at this code for 1 whole hour just to find out that the sentence missed 1 comma!?! Instead of “‘Invalid Planet Entry. Try: Mercury, Venus, Mars, Jupiter, or Saturn.’” I had “‘Invalid Planet Entry. Try: Mercury, Venus, Mars, Jupiter or Saturn.’” - try and spot my difference!

This is why sometimes it’s better to just copy and paste the string directly into your code!

Yeah, how exact it has to be is a bit much. even when my code is actually corrrect lol. I usually just glance at the solution and realize that I was right all along
