JSONDecodeError爬虫有道翻译

Question

新人求问啊啊啊啊啊~~~~下面是我的代码

import urllib.request
import urllib.parse
import json

content=input("请输入需要翻译内容：")
url="http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule"#？前面有个_o去掉才能正常使用 why？
data={}
data["i"]: content
data["type"]: "AUTO"
data["smartresult"]: "dict"
data["client"]: "fanyideskweb"
data["salt"]: "15482158645682"
data["sign"]: "91cbd7628c2de9065132acf3b88da8cd"
data["doctype"]: "json"
data["version"]: "2.1"
data["keyfrom"]: "fanyi.web"
data["action"]: "FY_BY_REALTIME"
data["typoResult"]: "true"

data=urllib.parse.urlencode(data).encode("utf-8")
response=urllib.request.urlopen(url,data)
html=response.read().decode("utf-8")
target=json.loads(html)
print("翻译结果是：%s"%(target["translateResult"][0][0]["tgt"]))

运行后的结果是
Traceback (most recent call last):
File "C:\Users\Administrator\Desktop\1.23.3.py", line 23, in
target=json.loads(html)
File "C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\lib\json__init__.py", line 354, in loads
return _default_decoder.decode(s)
File "C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\lib\json\decoder.py", line 339, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\lib\json\decoder.py", line 357, in raw_decode
raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
不知道该怎么改 求问大神

>>> import urllib.request
>>> import urllib.parse
>>> import json

>>> content=input("请输入需要翻译内容：")
请输入需要翻译内容：你好！我是豆子，你是谁？
>>> url="http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule"#？前面有个_o去掉才能正常使用 why？
>>> data={}
>>> data["i"]= content
>>> data["type"]= "AUTO"
>>> data["smartresult"]= "dict"
>>> data["client"]= "fanyideskweb"
>>> data["salt"]= "15482158645682"
>>> data["sign"]= "91cbd7628c2de9065132acf3b88da8cd"
>>> data["doctype"]= "json"
>>> data["version"]= "2.1"
>>> data["keyfrom"]= "fanyi.web"

>>>
>>> data=urllib.parse.urlencode(data).encode("utf-8")
>>> response=urllib.request.urlopen(url,data)
>>> html=response.read().decode("utf-8")
>>> target=json.loads(html)
>>> print("翻译结果是：%s%s"%(target["translateResult"][0][0]["tgt"], target["translateResult"][0][-1]["tgt"]))
翻译结果是：Hello!I am a beans, who are you?

最后一行，可以改一下，改一下中间啥的也行，使其输出不根据句号划分为不同的片段。
