调用response = urllib.request.urlopen(url,data)报错

liuzilongpy

新手调试了3个小时，python版本也和小甲鱼老师用的一样。按照教程视频中一个代码一个代码敲得，不知道为何报错如下信息，有爱心的大侠们帮帮我，不胜感激！！！！

源代码：
import urllib.request
import urllib.parse
url = 'http://fanyi.youdao.com/translate?smartresult=dict&smartresult=rule&smartresult=ugc&sessionFrom=http://dict.youdao.com/'
data = {'i': 'python', 'keyfrom': 'fanyi.web', 'type': 'AUTO', 'action': 'FY_BY_CLICKBUTTON', 'ue': 'UTF-8', 'doctype': 'json', 'xmlVersion': '1.8', 'typoResult': 'true'}

date = urllib.parse.urlencode(data).encode('utf-8')
response = urllib.request.urlopen(url,data)
html = response.read().decode('utf-8')
print(html)

报错信息：
>>>

    mv = memoryview(data)

楼主一定要细心啊
data date 傻傻分不清

1. date = urllib.parse.urlencode(data).encode('utf-8')  # 错误
   
2. data = urllib.parse.urlencode(data).encode('utf-8')  # 正确

多谢好心人帮助，代码可算调通了。我自己都苦笑不得。
