弄清楚了，通过使用以下内容，我们可以获得我需要的所有数据：

import dmidecode

def getBIOS():
    for v in dmidecode.bios().values():
        if type(v) == dict and v['dmi_type'] == 0:
            BIOSdict["Name"] = str((v['data']['Vendor']))
            BIOSdict["BuildNumber"] = str((v['data']['Version']))
            BIOSdict["SoftwareElementID"] = str((v['data']['BIOS Revision']))

我们迭代dmidecode.bios().values()来查找数据的每个字段。通过参考下表，我们可以查看要使用的功能。这也位于此链接中。

然后，我们检查的类型'v'以确保其为a dictionary （在我的情况下，这就是我所使用的），
然后检查'dmi_type‘是否是所搜索内容的正确代码。

例如：

       system      1, 12, 15, 23, 32

如果我们想获取BIOS信息，则可以参考v['dmi_type'] == 0该参考，这将返回一个字典。然后，我们可以创建自己的字典（以我BIOSdict = []为例），并按以下方式添加键和值：

BIOSdict["Name"] = str((v['data']['Vendor']))
