奇数和偶数

Question

I am getting an error when calculating odd and even numbers in range 2008 2009 2010 and 2011. Actually this code for calculate the winner of team A, every odd year the team will win. That why, in my code when its odd year, it will +1.

i = 0
sum = 0

n = list(map(int, input("Year : ").split()))
for i in n :
    if i % 2 != 0 :
        sum += 1
    else :
        sum = 0
print("Win :", sum)

# Input
2008 2009 2010 2011
# Output
1 (This is the problem, it should be 2 wins but i dont know why the output is always 1)

Answer 1

I think you don't need else:sum = 0 . You can continue with

i = 0
sum = 0

n = list(map(int, input("Year : ").split()))
for i in n :
    if i % 2 != 0 :
        sum += 1
  
print("Win :", sum)

Answer 2

A juanpa_arrivillaga tried to get you to notice, when you encounter an even year, you are setting the sum to 0. When it's an odd year, you are incrementing sum. Whenever you set the sum to 0, it undoes any incrementing you did in the previous iterations of the loop. Try printing sum out at the end of every loop and see if it says what you think it should say.

Answer 3

else :
    sum = 0

This statement is resetting the value of sum back to zero. Hence you can simply discard it.
