Fibonacci Series

def fib():
    a,b,c,l,n=-1,1,0,[],int(raw_input("enter the end of series:"))
    for i in range(n+1):
        c=a+b
        b,a=c,b
        l.append(c)
    n1=int(raw_input("enter the position:"))
    print l[n1-1]

if __name__=='__main__':
    fib() 

@msaisushma The only input I expect is the "nth" position. No "end of the series". For the fibanocci series: 0,1,1,2,3,5,8,13,21,34,55,89,...., input is 5, output is: 3

One other usecase:

Which Fibanocci number you want to check ?: 345
345 fibanocci number is:563963353180680437428706474693749258212475354428320807161115873039415970.
