Calculating phi ≈ 1.61803398874

I want to make a function to calculate phi (approximately equal to 1.61803398874 (i think))
i have already tried and came up with this but it doesn't work:

def phi():
    def fib(n):
        a,d,b=0,0,1
        while d<=n:
            c=a+b
            a=b
            b=c
            d+=1
        return float(c)
    e=1
    while True:
        print(long(fib(e)/fib(e-1))*10**(10+e))
        e+=1
        raw_input()
phi()

i need help
