Python Program for n-th Fibonacci number

1.Using recursion 

def Fibonacci(n): 
    if n<0: 
        print("Incorrect input") 
    # First Fibonacci number is 0 
    elif n==1: 
        return 0
    # Second Fibonacci number is 1 
    elif n==2: 
        return 1
    else: 
        return Fibonacci(n-1)+Fibonacci(n-2)   
print(Fibonacci(9)) 

2. Using Dynamic Programming 

FibArray = [0,1] 
  
def fibonacci(n): 
    if n<0: 
        print("Incorrect input") 
    elif n<=len(FibArray): 
        return FibArray[n-1] 
    else: 
        temp_fib = fibonacci(n-1)+fibonacci(n-2) 
        FibArray.append(temp_fib) 
        return temp_fib  
print(fibonacci(9))
