python 3 numbers of a range is even

lst = []

for i in range(1000,3001):
    flag = 1
    for j in str(i):          # every integer number i is converted into string
        if ord(j)%2 != 0:     # ord returns ASCII value and j is every digit of i
            flag = 0          # flag becomes zero if any odd digit found
    if flag == 1:
        lst.append(str(i))    # i is stored in list as string

print(",".join(lst))
