How do I delete or replace a file in a zip archive?

Question

I\'m creating a program in Python which downloads a set of files and puts them into an archive with the zipfile module.

I already found out how to append to the arch

Answer 1

From http://docs.python.org/2/library/zipfile

ZipFile.namelist()
Return a list of archive members by name.

So it is trivial to get hold of the members list before appending to the file and performing a check operation against the list of existing members within the archive.

In addition: removing from a ZIP file is not supported. You need to write a new archive if needed and copy over existing files and omit the file to be removed.
