How do you know it is when unzipping the file? Maybe it is, or maybe it
isn't. The line giving the error has *two* IO operations, a read and a
write. Either one could give IOError.
outfile.write(z.read(name))
IOError: (22, 'Invalid argument')
The first thing is to isolate what is causing the error:
data = z.read(name)
outfile.write(data)
Now you can be sure whether it is the read or the write which causes
the
error.
Secondly, find out what the argument is. Assuming it is the read, try
this:
print repr(name)
Can you open the zip file in Winzip or some other zip utility? Does it
need a password?
I see you do this:
fh = open('T:\\test\\*.zip', 'rb')
Do you really have a file called *.zip? I find that very hard to
believe... as I understand it, * is a reserved character in Windows and
you cannot have a file with that name.
My guess is that the actual error is when you try to open the file in
the
first place, before any unzipping takes place, but you've messed up the
line numbers (probably by editing the file after importing it).

The problem is happening when it is coming to write option.
The * is not the real name of the zip file, I just hide the name.
