Here you want to open a.zip as a text file (default) for appending, in
both read and write mode.

I think sufficient would be

f=open("d:\\a.zip",'wb')

For opening a new file and writing as binary.

Then you will want:

f.write(content)

f.close()

thank james;
and I have got a way to resolve it :
urllib.urlretrieve('http://x.x.x.x/library.zip','library.zip')

but I want to ask: how to find out explaination about the parameters of
'open()' function?

Uhm... Read the Python Library documentation?

Or type "help(open)" at a Python interpreter console prompt...
