Python - nested append not working in If statement

I am new to Python so bear with me here. My evenList is not being populated for some reason. I know the loop is executing because when I add a print statement under my if then it prints 4 times. My oddList is appending just fine.

def find_outlier(integers):

    evenList = []
    oddList = []
    for i in range(len(integers)):
        if (integers[i] % 2) == 0:
            evenList.append(integers[i])
        else:
            oddList.append(integers[i]) 
    if len(evenList) < len(oddList):
        print(evenList[0])
    else:
        print(oddList[0])

testList = [2,6,8,10,3]

find_outlier(testList)
