代码实现：
def write_file():
like_num = input(‘请输入您喜欢的数字：‘)
with open(‘C:\\Users\\Administrator\\Desktop\\data.json‘,‘w‘) as fw:
json.dump(like_num,fw) # 将内容写入文件
with open(‘C:\\Users\\Administrator\\Desktop\\data.json‘,‘r‘) as fr:
data = json.load(fr) # 读取文件内容
return data
data = write_file()
print("I know your favorite number! It‘s {}.".format(data))
dumps() 和loads()
data = {‘key1‘:1,‘key2‘:2}
print(json.dumps(data)) #{"key1": 1, "key2": 2}
print(json.loads(json.dumps(data))) #{‘key1‘: 1, ‘key2‘: 2}
