Even Fibonacci numbers

Problem 2

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.

Answer:

 def isEven(a):

     if a%2 == 0:

         return True

     return False

 Max = 4000000

 a = 0

 b = 1

 c = 0

 count = 0

 while True:

     c = a + b

     if(c > Max):

         break

     if isEven(c):

         count += c

     a = b

     b = c

 print("the result is ", count)
