json模块中dumps()与dump()区别
dumps()与dump()区别
dumps是将dict转化成json字符串格式,loads是将json字符串转化成dict格式。
dump和load也是类似的功能,只是与文件操作结合起来了。
dump(写入内容,文件对象) 和load(文件对象)
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}
