            Hello Guys, my this code passes the 3 test cases, can anyone tell me how to solve the all cases?

if year % 100 == 0: if year % 400 != 0: return False else: return True elif year % 4 == 0: return True else: return False

if year % 100 == 0: if year % 400 != 0: return False else: return True elif year % 4 == 0: return True else: return False

def is_leap(year): leap = False

if year % 4 == 0:
    if year % 100 == 0:
        if year % 400 == 0:
            leap = True
    else:
        leap = True

return leap

year = int(input()) print(is_leap(year))
