Python winreg-如何将换行写入REG_SZ值

我需要一些帮助来向注册表值写入换行符。该值的类型为REG_SZ

在注册表中修改十六进制值时，我可以通过向每个中断位置添加“0A”手动完成此操作，但我不确定如何以编程方式完成此操作

这是我当前将字符串写入注册表的代码，它可以工作，但不允许换行：

（对标识信息进行编辑，并缩短文本。“#”是换行符的位置）

导入操作系统
导入_winreg
从winreg导入*
Key=r“软件\Microsoft\Windows\CurrentVersion\Policys\System”
字段=[\u winreg.REG\u SZ，\u winreg.REG\u二进制]
Sub_Key=[“legalnoticetext”，
“法律公告选项”]
值=[“使用条款”，
“通过登录到此电脑，用户同意使用条款”
\n用户同意以下内容：#-用户不得以任何方式更改
“未经任何授权人员批准，在本电脑上进行设置。”]
parmLen=len（子键）
z=0#列表迭代的循环计数器
尝试：
Key=r“软件\Microsoft\Windows\CurrentVersion\Policys\System”
如果操作系统路径不存在（键）：
key=\u winreg.CreateKey（HKEY\u本地\u机器，key）
Registrykey=OpenKey（HKEY_本地_机器，密钥，0，密钥写入）
而z

我测试了以下代码以查看是否可以直接用十六进制编写，因为我修改了十六进制值，但它会导致值被解释为字符串，然后将其错误地（再次）格式化为十六进制

RTFM'ing在这个具体问题上并没有太大帮助，所以任何指导都将不胜感激

你有几个问题

os.path.exists

检查文件路径是否存在。输入键字符串不会检查注册表

看起来你正在使用Python 2.7，请考虑升级到3。您遇到的问题是编写

REG\u二进制文件

需要二进制数据；在Python3中，这意味着您只需要对字符串进行编码。下面是Python 3中的代码

导入winreg
Key\u str=r“软件\Microsoft\Windows\CurrentVersion\Policys\System”
字段=[winreg.REG\u SZ，winreg.REG\u二进制]
子_键=[“法律公告文本”，“法律公告选项”]
值=[“使用条款”，
“通过登录到此电脑，用户同意使用条款”
\n用户同意以下内容：#-用户不得以任何方式更改
“未经任何授权人员批准，在本电脑上进行设置。”]
尝试：
key=winreg.OpenKey（winreg.HKEY\u LOCAL\u MACHINE，key\u str）
除FileNotFoundError外：
key=winreg.CreateKey（winreg.HKEY\u LOCAL\u MACHINE，key\u str）
对于zip中的sk、f、v（子键、字段、值）：
如果f==winreg.REG\u二进制：
winreg.SetValueEx（键，sk，0，f，v.encode（'latin-1'））
其他：
winreg.SetValueEx（键，sk，0，f，v）
key.Close（）

在Python2中，标准字符串是字节字符串，因此不需要将字符串编码为字节编码。以下是Python 2代码：

import\u winreg
Key\u str=r“软件\Microsoft\Windows\CurrentVersion\Policys\System”
字段=[\u winreg.REG\u SZ，\u winreg.REG\u二进制]
子_键=[“法律公告文本”，“法律公告选项”]
值=[“使用条款”，
“通过登录到此电脑，用户同意使用条款”
