Finding the sum of even valued terms in fibonacci sequence using for loop

Question

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

prev, cur = 0, 1
total = 0
while True:
    prev, cur = cur, prev + cur
    if cur >= 4000000:
        break
    if cur % 2 == 0:
        total += cur
print(total)

How can i solve this using for loop?

Answer 1

The Fibonacci sequence reaches 4000000 from the 34th element

prev, cur = 0, 1
total = 0
for i in range(34):
    prev, cur = cur, prev + cur
    if cur % 2 == 0:
        total += cur
print(total)

Answer 2

first = 0
second = 1
for i in range(1,4000000):
    next=(first+second)
    print(next)
    first=second
    second=next
