Leap Year

Question

I made this code to determine whether a year was a leap year but when I ran it it failed 4 out of the seven test cases. The first condition was for it to be divide by 4, then 100 then 400.
This is the code:
year = int(input())
if year % 4 == 0:
if year % 100 == 0:
if year % 400 == 0:
print('Leap year')
else:
print('Not a leap year') I was confused whether the conditions should be separated or if the year has to meet all the conditions before it can be considered a leap year.

Answer 1

Hi! If the year is not divided without a residue by 100, then it is leap, but you have the opposite

Answer 2

Add a proper else parts for first 2 outer if parts..
"Otherwise..." part missing.
