斐波那契数列,又称黄金分割数列,从第三项开始,每一项都等于前两项之和
F0 = 0
F1 = 1
F2 = Fn-1 + Fn-2
请写一个函数find_mth_fibo(n) 在斐波那契数列里返回第N个数值 如find_mth_fibo(3) 则返回数值2 find_mth_fibo(10)则返回 55
def find_mth_fibo(n): if n == 1: return 1 elif n == 2: return 1 elif n > 2: return find_mth_fibo(n - 1) + find_mth_fibo(n - 2) if __name__ == '__main__': print(find_mth_fibo(10))
