如下代码，跟公众号里代码类似，content能打印出来，但是data打印就会报错。请问是哪里出了问题？？
代码如下：
import urllib.request
import json
from city import city   #前一个是模块名，自定义模块。后一个是变量名

print("你想要查询的城市")
one_city=input("请输入：")
citycode=city.get(one_city)
if citycode:
    web=urllib.request.urlopen("http://www.weather.com.cn/data/cityinfo/%s.html"%citycode)
    content=web.read()
    print(content)
    data=json.loads(content)
    print(data)

run之后，报错如下：
=== RESTART: C:/Users/MyPC/AppData/Local/Programs/Python/Python36/查天气1.py ===
你想要查询的城市是
请输入：北京
b'{"weatherinfo":{"city":"\xe5\x8c\x97\xe4\xba\xac","cityid":"101010100","temp1":"18\xe2\x84\x83","temp2":"31\xe2\x84\x83","weather":"\xe5\xa4\x9a\xe4\xba\x91\xe8\xbd\xac\xe9\x98\xb4","img1":"n1.gif","img2":"d2.gif","ptime":"18:00"}}'

在代码
print(content)
后面加一行，转换成str即可。
content = content.decode('utf8')

问题已解。。
