fibonacci recursive python

#fibonacci sequence with memory to increase the speed.
class recur_fibo:
    memory = {0: 1, 1:1}
    
    def fibonacci(n):
        if n in recur_fibo.memory:
            return recur_fibo.memory[n]
        else:
            recur_fibo.memory[n] = recur_fibo.fibonacci(n-1) + recur_fibo.fibonacci(n-2)
            return recur_fibo.memory[n]

if __name__ == "__main__":
    value = recur_fibo.fibonacci(200)
    print(value)
