蟒。如何修复错误："print tablecsv.read() AttributeError: 'tuple' object has no attribute 'read"

Question

我学习Python并尝试对html表进行解析，然后我将创建。csv文件以将数据导入mySQL。

>>> 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，我创建csv文件，有错误。

>>> 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，我不能理解何时以及如何创建元组。有人能告诉我什么时候我错了，怎么补救吗?

Answer 1

您错过了这里的方法名称:tablecsv = (r'/tmp/table.csv', 'r')，即您可能想要打开文件。e。g tablecsv = open(r'/tmp/table.csv', 'r')

在使用tablecsv.close()

读取之前，还应该在写入后关闭文件。

如果你只是在括号中有一个项目列表，例如(r'/tmp/table.csv', 'r')，那么这将创建一个元组
