Decompressing a .bz2 file in Python

Question

So, this is a seemingly simple question, but I\'m apparently very very dull. I have a little script that downloads all the .bz2 files from a webpage, but for some reason the dec

Answer 1

openZip = open(zipFile, "r")

If you're running on Windows, you may want to do say openZip = open(zipFile, "rb") here since the file is likely to contain CR/LF combinations, and you don't want them to be translated.

newLine = openZip.readline()

As Alex pointed out, this is very wrong, as the concept of "lines" is foreign to a compressed stream.

s = fileHandle.read(1024) [...] uncompressedData += bz2.decompress(s)

This is wrong for the same reason. 1024-byte chunks aren't likely to mean much to the decompressor, since it's going to want to work with it's own block-size.

s = fileHandle.read() uncompressedData = bz2.decompress(s)

If that doesn't work, I'd say it's the new-line translation problem I mentioned above.
