Python zipfile dosen't release zip file

Question

I\'m trying to use zipfile library on windows 8.1 and python 2.7.9.

I just want to remove library.zip after zipfile.open() but os.remove() throws \"WindowsError [Err

I think you must close your archive before deleting it or exiting the program as it says in python documentation https://docs.python.org/2/library/zipfile.html#zipfile.ZipFile.close

So run z1.close() and z2.close() before removing an archive

Your code must look like this:

import os
import zipfile as z

dirs = os.listdir('build/')
bSystemStr = dirs[0]

print("[-] Merging library.zip...")
with z.ZipFile('build/' + bSystemStr + '/library.zip', 'a') as z1:
    with z.ZipFile('build_temp/' + bSystemStr + '/library.zip', 'r') as z2:
        for t in ((n, z2.open(n)) for n in z2.namelist()):
            try:
                z1.writestr(t[0], t[1].read())
            except:
                pass

         z2.close()

     z1.close()


print("[-] Cleaning temporary files...")
os.remove('build_temp/' + bSystemStr + '/library.zip')

If I'm wrong, correct me.
