Python: Even Fibonacci Numbers
Python: Even Fibonacci Numbers
ProjectEuler Problem No.2
Easy fast task in ProjectEuler, The Task is to find the sum of the even-valued terms in Fibonacci sequence whose values do not exceed four million.
In this code we will add some print-statment to just show how mane even numbers there and the summation of it.

The Code:
# Even Fibonacci Numbers
# projectEuler Problem No. 2
def get_fibonacci_sequence():
n1 = 1
n2 = 1
fibo = 1
while fibo < 4000000:
fibo = n1+n2
n1 = n2
n2 = fibo
if fibo% 2 == 0:
even_fibo_num.append(fibo)
tot = 0
even_fibo_num = []
get_fibonacci_sequence()
print(‘\n We fond {} even fibonacci”s number less than 4000000.’.format(len(even_fibo_num)))
for each in even_fibo_num:
tot = tot + each
print(‘ The summation on those even Fibonacci”s is: ‘, tot)
