Why does round(2.5) return 2?

Question

Using python 3

round(2.5) # 2

Shouldn't it return 3?

I tried using python 2 and it gave me the correct result

round(2.5) # 3

Answer 1

Found this in the python documentation: if two multiples are equally close, rounding is done toward the even choice 

Try print(round(3.5)) it is 4.

Or try this:

for i in range (0, 100):
print(round(i + 0.5))
