Extracting .zip files with Python

[Ray Parrish]

Hello,

Here I am stuck again... 8-) Here's my code as ran in the interpreter,
and the errors -

ThisZip = zipfile.ZipFile("/home/ray/logs/IIS/ex100102.zip", "r")
List = ThisZip.namelist()
List[0]

'ex100102.log'

ArchiveName = List[0]
ThisZip.extract(ArchiveName,"/home/ray/logs/IIS/" + ArchiveName)

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: ZipFile instance has no attribute 'extract'

FileHandle = ThisZip.open(ArchiveName,"r")

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: ZipFile instance has no attribute 'open'

I think the documents actually said that .extract() was a Python 2.6
thing, and since I'm on Python 2.5 I guess it doesn't have that, but it
should have .open() as it was listed above the 2.6 version seperation in
the docs.

Can you please tell me what I'm doing wrong, and give me some pointers
on extracting .zip files with the Python zipfile class?

Thanks, Ray Parrish

http://docs.python.org/library/zipfile.html?highlight=zipfile#zipfile.ZipFile.open
says "New in version 2.6".

Use ThisZip.read(filename) to get the contents as a Python string, then
write it out to a file.

As a rule of thumb, I reckon Python to be an order of magnitude more wasteful
of CPU cycles and memory than my favourite low-level language, C++.
