在json/decoder.py中提示“No JSON object could be decoded”，所以在read()方法中要返回具有json格式的原始字符串，最简单的就是[]

我这种方法效率挺低的：
def __init__(self, num):
if num==1 :
self.numbers=[0]
elif num==2:
self.numbers=[0,1]
else :
g=Fib(num-1)
g.numbers.append(g.numbers[-1]+g.numbers[-2])
self.numbers=g.numbers
def __init__(self, num):
if num==1 :
self.numbers=[0]
elif num==2:
self.numbers=[0,1]
else :
g=Fib(num-1)
g.numbers.append(g.numbers[-1]+g.numbers[-2])
self.numbers=g.numbers
