[Tutor] file?

[kakada]

Hi all,

How can we know that one specific file is already exist in filesystem?
for instance, I want to read zipfile by issuing code:

import zipfile
ziparchive = zipfile.ZipFile(inputfilename, "r")

if the inputfilename doesn't exist then an error would be occurred.
I want to catch up this special case first.

Thanks,
da
