Python Dict-多个实例或“Sub Dict”问题-以编程方式添加项

我最终想用的一个词是:

    host_dict = {
    'installed_applications':
    {
        'name': 'alsdfasdf',
        'version': '1',
        'installed_date': '11-11-11',
    }
    {
        'name': 'alsdfasdf',
        'version': '1',
        'installed_date': '11-11-11',
    }
    {
        'name': 'alsdfasdf',
        'version': '1',
        'installed_date': '11-11-11',
    }
        {
        'name': 'alsdfasdf',
        'version': '1',
        'installed_date': '11-11-11',
    }
}

我想做的是:

host_dict = {}
apps = get_installed_apps(host)
host_dict['installed_applications'] = {}
for app in apps:
    host_dict['installed_applications']['name'] = app[0]
    host_dict['installed_applications']['version'] = app[1]
    host_dict['installed_applications']['uninstall_string'] = app[2]
    host_dict['installed_applications']['install_date'] = app[3]
    host_dict['installed_applications']['install_location'] = app[4]
    host_dict['installed_applications']['publisher'] = app[5]

问题是它没有附加应用程序的每个实例,只是在编写一个“sub dict”(这就是您所说的吗?)
