Modifying the Windows registry with a Python operation is obviously easier than using C or C + +.

Main reference: Official document: Http://docs.python.org/library/_winreg.html

There are two main ways to manipulate the registry through Python, one is through Python's built-in module _winreg, and the other is Win32 Extension for Python's Win32API module. Here is a simple look at how to operate the registry with the built-in module _winreg.

1. Read

The method of reading is the Openkey method: Open a specific key

_winreg. Openkey (Key,sub_key,res=0,sam=key_read)

Example: This example is a list of registry keys that show the native network configuration

#!/usr/bin/env python

#coding =utf-8

Import _winreg

Key = _winreg. Openkey (_winreg. HKEY_LOCAL_MACHINE, R "system\currentcontrolset\services\tcpip\parameters\interfaces\{0e184877-d910- 4877-b 4c2-04f487b6dbb7} ")

#获取该键的所有键值, iterating through enumerations

Try

I=0

While 1:

#EnumValue方法用来枚举键值,EnumKey is used to enumerate sub-keys

Name,value,type = _winreg. Enumvalue (Key,i)

Print repr (name), Value,type

I+=1

Except Windowserror:

Print

#假如知道键名, you can also take a value directly

Value,type = _winreg. QueryValueEx (Key, "DhcpDefaultGateway")

Print "Default gateway address ----", Value,type

The results of the operation are as follows:

' UseZeroBroadcast ' 0 4

' EnableDeadGWDetect ' 1 4

' EnableDHCP ' 1 4

' IPAddress ' [u ' 0.0.0.0 '] 7

' SubnetMask ' [u ' 0.0.0.0 '] 7

' Dhcpretrystatus ' 0 4

' Dhcpnameserver ' 10.0.0.10 1

' DhcpDefaultGateway ' [u ' 10.104.4.1 '] 7

' Dhcpsubnetmaskopt ' [u ' 255.255.254.0 '] 7

Default gateway address ----[u ' 10.104.4.1 '] 7

2. Create a Modify registry

Create key:_winreg. CreateKey (Key,sub_key)

Delete key: _winreg. DeleteKey (Key,sub_key)

Delete key value: _winreg. DeleteValue (Key,value)

Assign a value to the new key: _winreg. SetValue (key,sub_key,type,value)

Example:

#!/usr/bin/env python

#coding =utf-8

Import _winreg

Key=_winreg. Openkey (_winreg. Hkey_current_user,r "Software\microsoft\windows\currentversion\explorer")

#删除键

_winreg. DeleteKey (Key, "advanced")

#删除键值

_winreg. DeleteValue (Key, "Iconunderline")

#创建新的

NewKey = _winreg. CreateKey (Key, "Mynewkey")

#给新创建的键添加键值

_winreg. SetValue (NewKey, "ValueName", 0, "valuecontent")
