This is my code:
def sum_even(a, b):
count = 0
for i in range(a, b, 1):
if(i % 2 == 0):
count += [i]
return count
An example I put was print(sum_even(3,7)) and the output is 0. I cannot figure out what is wrong.
Your indentation is off, it should be:
def sum_even(a, b):
count = 0
for i in range(a, b, 1):
if(i % 2 == 0):
count += i
return count
so that return count
doesn't get scoped to your for loop (in which case it would return on the 1st iteration, causing it to return 0)
(And change [i]
to i
)
NOTE: another problem - you should be careful about using range
:
>>> range(3,7)
[3, 4, 5, 6]
so if you were to do calls to:
sum_even(3,7)
sum_even(3,8)
right now, they would both output 10
, which is incorrect for sum of even integers between 3 and 8, inclusive.
What you really want is probably this instead:
def sum_even(a, b):
return sum(i for i in range(a, b + 1) if i % 2 == 0)
