我在Windows 7(64位)上使用Python 2.7.当我尝试用ZipFile模块解压缩zip文件时,我收到以下错误: -
Traceback (most recent call last):
File "unzip.py", line 8, in <module>
z.extract(name)
File "C:\Python27\lib\zipfile.py", line 950, in extract
return self._extract_member(member, path, pwd)
File "C:\Python27\lib\zipfile.py", line 993, in _extract_member
source = self.open(member, pwd=pwd)
File "C:\Python27\lib\zipfile.py", line 897, in open
raise BadZipfile, "Bad magic number for file header"
zipfile.BadZipfile: Bad magic number for file header
WinRAR可以提取我试图提取的文件.这是我用来从中提取文件的代码myzip.zip
from zipfile import ZipFile
z = ZipFile('myzip.zip') //myzip.zip contains just one file, a password protected pdf
for name in z.namelist():
z.extract(name) …我在Windows 7(64位)上使用Python 2.5.

application.listen(8888)
tornado.ioloop.IOLoop.instance().start()
我收到以下错误: -
