关于函数的调用

[b]urllib.parse.urlencode(query, doseq=False, safe='', encoding=None, errors=None, quote_via=quote_plus) [/b]
Convert a mapping object or a sequence of two-element tuples, which may contain str or bytes objects, to a percent-encoded ASCII text string. If the resultant string is to be used as a data for POST operation with the urlopen() function, then it should be encoded to bytes, otherwise it would result in a TypeError.

关于urllib.parse.urlencode(query, doseq=False, safe='', encoding=None, errors=None, quote_via=quote_plus) 函数，我想对encoding 进行设定，
data=urllib.parse.urlencode(data,encoding='UTF-8')
结果报错：

Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\爬虫\2.有道词典\translation.py", line 24, in <module>
    response=urllib.request.urlopen(url,data)
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 223, in urlopen
    return opener.open(url, data, timeout)
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 524, in open
    req = meth(req)
  File "C:\Users\Administrator\AppData\Local\Programs\Python\Python36\lib\urllib\request.py", line 1248, in do_request_
    raise TypeError(msg)
TypeError: POST data should be bytes, an iterable of bytes, or a file object. It cannot be of type str.

代码更改后：
data=urllib.parse.urlencode(data).encode=('UTF-8')
就没有问题了，上面的设定方法不对吗？
