Python之注册表增删改查（干货）

在Windows平台下，对注册表的增删改查的需求比较多，微软提供了很多用于访问，修改注册表等的API，我们可以使用诸如bat，或者C++等各种方式去访问修改注册表。无所不能的python下如何完成这些操作呢？pywin32模块中提供了与微软提供的C++等语言API一致的使用python对注册表进行操作的接口。今天带给大家的是对注册表进行修改的代码（PS:想使用的孩纸直接复制拿走，亲测可用！）需要的孩纸们直接看代码：

 import win32api, win32con
 import sys

 __author__ = 'Berlin'

 def ModifyReg(key, keyPath, valueName, valueType, value):
     try:
         '''
         RegConnectRegistry:
             computerName: string(If None, the local computer is used)
             key: int(May be win32con.HKEY_LOCAL_MACHINE...)
         '''
         keyHandle = win32api.RegConnectRegistry(None, key)
         '''
         RegOpenKeyEx:
             key: PyHKEY/int
             subKey: string
             reserved = 0: int(Reserved. Must be zero.)
             sam = KEY_READ: int(If you want to set the value later, you must open the key with KEY_SET_VALUE)
         '''
         subkeyHandle = win32api.RegOpenKeyEx(keyHandle, keyPath)
         '''
         RegQueryValueEx:
             key: PyHKEY/int
             valueName: The name of the value to query
         '''
         (currValue, type) = win32api.RegQueryValueEx(subkeyHandle, valueName)
         if (currValue == value):
             print 'PASS: Check reg value: %s' % valueName
             return 1
         else:
             print 'INFO: The %s is not the same as %s' % (valueName, value)
             print 'INFO: Try to set %s as %s' %(valueName, value)
             subkeyHandle = win32api.RegOpenKeyEx(keyHandle, keyPath, 0, win32con.KEY_SET_VALUE)
             '''
             RegSetValueEx:
                 key: PyHKEY/int
                 valueName: string(The name of the value to set)
                 reserved: any(Zero will always be passed to the API function)
                 type: int(REG_DWORD, REG_SZ ...)
                 value: registry data
             '''
             win32api.RegSetValueEx(subkeyHandle, valueName, 0, valueType, value)
     except:
         print 'FAIL: ModifyReg %s. Exception happened. Exception happened when accessing registry key under %s.' % (valueName, keyPath)
         return 0
     print 'SUCCESS: ModifyReg %s value under %s' % (valueName, keyPath)
     return 1

 def main():
     key = win32con.HKEY_LOCAL_MACHINE
     AUPath = r'SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update'
     valueName = r'AUOptions'
     valueType = win32con.REG_DWORD
     value = 1
     ModifyReg(key, AUPath, valueName, valueType, value)

 if __name__ == '__main__':
     sys.exit(main())

实例是修改Windows自动更新的注册表项，将其修改为1.
