def sum_even(a):
	sum = 0
	for num in a:
		if num%2 == 0:
			sum+=num
	return sum

def super_sum(a):
	sum = 0
	for num in a:
		num = str(num)
		for i in num:
			i = int(i)
			sum+=i
	return sum

print(sum_even([10, 5, 6, 1]))
print(super_sum([120, 13, 45]))

Looks good! The only thing is that you are using the sum keyword. So if your program was using sum inbuilt function anywhere, it will be overridden.
