按照老師講的寫的代碼，報錯如下：怎么回事呢？

D:\Python36\python.exe D:/PycharmProjects/urltest/urlpost.py

Traceback (most recent call last):

? File "D:/PycharmProjects/urltest/urlpost.py", line 11, in <module>

? ? ("SearchWay", "DepartureInMandarin")

TypeError: 'tuple' object is not callable

源代碼：

from urllib.request import urlopen
from urllib.request import Request
from urllib import parse

req = Request("http://www.thsrc.com.tw/tw/TimeTable/SearchResult")
postData= parse.urlencode([
? ?("StartStation", "977abb69-413a-4ccf-a109-0272c24fd490"),
? ?("EndStation", "9c5ac6ca-ec89-48f8-aab0-41b738cb1814"),
? ?("SearchDate", "2017/02/17"),
? ?("SearchTime", "19:00")
? ?("SearchWay", "DepartureInMandarin")
])
req.add_header("Origin", "http://www.thsrc.com.tw")

resp = urlopen(req, data=postData.encode("utf-8"))

print(resp.read().decode("utf_8"))
