Got the hint. I have tried to follow the hint but it seems that there's some problem with the tool I am using :(

Lovely challenge :)

Really loved this one, very original (had never seen one like that ; and as said below, the challenge is practically solved once you understand the pun in the hint, could almost regret there is not another step behind ^^)

Finally solved. Loved this challenge too much

Tries this in Excel for instance ;)

You are on right way

Nice challenge

i think it cant to solve without any experience with pandas

Haha, great challenge, but for people who are not native English speakers (me) can be a bit confusing :D

Hi Rivit! Cool that you enjoyed it. My mother tongue is not English too. I tried to give a hint with a play on words and I hope that my broken English is okayish. ?

Finally solved. Loved this challenge too much

Nice challenge

Didn't use Excel or numpy. Just play with the numbers using basic operations...

I actually enjoyed this challenge, for which I really appreciate @ebouteillon.

Nice to hear ;)

I never thought I'd solve a challenge with Excel

I like creative challenges and solutions :)

Excellent challenge ebouteillon! I loved it!
