蟒蛇。 如何解決錯誤：“ print tablecsv.read（）AttributeError：“ tuple”對象沒有屬性“ read”

Question

我選擇Python並嘗試為html表做解析器，然后我將不會創建.csv文件以將數據導入到mySQL中。

>>> htmlread = handlestatbydate.read()
>>> soup = BeautifulSoup("".join(htmlread))
>>> souptable = soup('tbody', limit=2)[1].findAll('tr')
>>> souptablestr = ''.join(str(t) for t in souptable)
>>> reclearbyonce = re.compile('</tr><tr>\n|^<tr>\n|</tr>$')
>>> recleartd = re.compile(r'</td>|<td.*?>')
>>> retdtd = re.compile('""| ')
>>> soupclearbyonce = reclearbyonce.sub('', souptablestr)
>>> soupcleartd = recleartd.sub('"', soupclearbyonce)
>>> souptdtd = retdtd.sub('","', soupcleartd)
>>> print souptdtd
"59","00059413","00059413","70000000001","2011-08-22","18:01:48","0:07","0.45"
"60","00059413","00059413","70000000002","2011-08-22","18:49:48","0:43","1.95"
"61","00059413","00059413","70000000003","2011-08-22","18:52:50","5:07","11.70"
"62","00059413","00059413","70000000003","2011-08-22","19:02:47","4:10","9.75"

然后，我創建了csv文件並出現錯誤。

>>> tablecsv = file(r'/tmp/table.csv', 'w')
>>> tablecsv.write("".join(souptdtd))
>>> tablecsv = (r'/tmp/table.csv', 'r')
>>> print tablecsv.read()

    print tablecsv.read()
AttributeError: 'tuple' object has no attribute 'read

不幸的是，我無法理解何時以及如何創建元組。 當我弄錯了以及如何解決它時，有人可以向我解釋嗎？

Answer 1

您在這里錯過了方法名稱： tablecsv = (r'/tmp/table.csv', 'r')即您可能想打開文件。 tablecsv = open(r'/tmp/table.csv', 'r')

您還應該在寫入后關閉文件，然后再使用tablecsv.close()從文件中讀取

如果您僅在方括號中包含項目列表，例如(r'/tmp/table.csv', 'r')則會創建一個元組。
