Python 默认情况下提取zip覆盖？

我有以下代码：

pz = open(packagezip, 'rb')

packz = zipfile.ZipFile(pz)
for name in packz.namelist():
    packz.extract(name, package_ext_loc)

pz.close()

如果要从中提取的文件（packagezip）在目标位置（package_ext_loc）遇到同名文件夹，此函数是否会自动覆盖文件夹和文件，因为这是我想要的，如果不是，是否有一个简单的附加脚本来强制执行此操作

在浏览了一些网站之后，我相信如果目标文件夹已经存在，zipfile.extractall会被覆盖。在本例中，我如何使用extractall。

我已经测试了您的代码，它运行良好。这意味着每次我运行代码时，它都会覆盖文件夹中相同的现有文件。

我已经绕了一圈，确保如果有重复的文件夹，它们会像这样被删除

packagezip = xbmc.translatePath('special://home/userdata/addon_data/plugin.program.super.favourites/Super Favourites/Maintenance/packages/packages.zip')

        adz.close()
    else:
        xbmc.executebuiltin("Notification(No addondata, at this time,()")

我不确定zipfile是否会自动覆盖
