Include a directory structure in a zip file based on a fixed relative path

Question

Given the directory at a path a:\\b\\c\\d\\e, I want to create a zipfile in python 3.5+ that looks like this:

file.zip # want this
 +d
  +-...files from d\
  +-e
    +-...files from e\

I tried this by walking the target path like this, using os and zipfile:

start_path = "a:\\b\\c\\d"

for root, dirs, files in os.walk(start_path):
    for file in files:
        ziph.write(os.path.relpath(os.path.join(root, file)))

Due to the the relpath and working dir being in b, the code will create a zip file as follows:

file.zip # do not want this
 +c
  +-...files from c\
  +-d
    +-...files from d\
    +-e
      +-...files from e\

My Question is: How can I force the zipwriter to create a directory structure as shown at the beginning, starting with dir d while I know the full path only at runtime.

ZipFile.write accepts a second parameter, which is the directory you want it to be in inside the zip. So you can have something like:

start_path = "a:\\b\\c\\d"
import os
zip_start_path = start_path.split(os.sep)[-1]

Thank you! I seem to have overlooked that arcname parameter. Could I make the path splitting seperator os independent?

Yep, you get the separator with os.sep (docs.python.org/3/library/os.html#os.sep)
