Python zipfile不会发布zip文件

我正在尝试在Windows 8.1和python 2.7.9上使用zipfile库.

我只想在zipfile.open()之后删除library.zip,但是os.remove()抛出“ WindowsError [Error 32]”,并且似乎zipfile不会将zip文件与block一起释放.

WindowsError 32的意思是“该进程无法访问该文件,因为该文件正在被另一个进程使用.”

那么,如何删除此library.zip文件？

码：

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

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

错误：

解决方法:

我认为您必须先删除归档文件,然后才能删除它或退出程序,如python文档https://docs.python.org/2/library/zipfile.html#zipfile.ZipFile.close中所述

因此,在删除档案之前运行z1.close()和z2.close()

您的代码必须如下所示：

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')

如果我错了,请纠正我.
