# Pandas pandas pandas project in Data Science course

My code is not working for test case 3. I tried to revise the code again and again but I don’t know what is wrong here. Can anybody give me a clue where my code went wrong? Also does anybody know what is the test case 3? https://code.sololearn.com/c6w3kYK2HrOu/?ref=app

if n1 or n2 is null you will have an error on line 25 or line 26. I suggest you, before calculating the means to first test if those numbers are not null.
I suppose that in this test, one of your variables n1 or n2 will be null.

for j in points:

else :

print(mask2.round(2))
hi every one I tried this but I got the same error, in case number 3, I don't know what to do ? if any one could help me pass it, I'll be happy.
