Loop through values or registry key.. _winreg Python
提问by Zac Brown
How would I loop through allthe valuesof a Windows Registry Key using the Python module _winreg. I have code that will do what I want, but it is for the subkeys of the specified registry key.
如何将通过我环路所有的值使用Python模块_winreg一个Windows注册表项。我有代码可以做我想做的事，但它是针对指定注册表项的子项的。
Here Is The Code:
这是代码：
from _winreg import *
t = OpenKey(HKEY_CURRENT_USER, r"PATH TO KEY", 0, KEY_ALL_ACCESS)
try:
i = 0
while True:
subkey = EnumValue(t, i)
print subkey
i += 1
except WindowsError:
# WindowsError: [Errno 259] No more data is available
pass
Oh, figured it out. But, if anyone knows of another way to do it, I'll still accept that answer!
哦，想通了。但是，如果有人知道另一种方法来做到这一点，我仍然会接受这个答案！

Shouldn't EnumValue be of help here
EnumValue 不应该在这里有帮助
# list all values for a key
try:
count = 0
while 1:
name, value, type = _winreg.EnumValue(t, count)
print repr(name),
count = count + 1
except WindowsError:
pass

I prefer to avoidthe error instead of diving right into it ...
我宁愿避免错误，而不是一头扎进去......
Use _winreg.QueryInfoKeyto get the number of values:
使用_winreg.QueryInfoKey获取值的数量：
import _winreg
key = _winreg.OpenKey(_winreg.HKEY_CURRENT_USER, r'PATH\TO\KEY', 0, _winreg.KEY_READ)
for i in xrange(0, _winreg.QueryInfoKey(key)[1]):
print _winreg.EnumValue(key, i)
To get the number of Keys, same method, different index (second half of original question):
要获取键的数量，方法相同，索引不同（原始问题的后半部分）：
for i in xrange(0, _winreg.QueryInfoKey(key)[0]):
print _winreg.EnumKey(key, i)
Note:use importinstead of from ... importto make it explicit where functions and variables are coming from. Makes it easier to follow code later in life.
注意：使用import代替from ... import来明确函数和变量的来源。更容易在以后的生活中遵循代码。

import winreg
hKey = winreg.OpenKey(winreg.HKEY_CLASSES_ROOT, "Local Settings\Software\Microsoft\Windows\Shell\MuiCache")
try:
count = 0
while 1:
name, value, type = winreg.EnumValue(hKey, count)
print (name),
count = count + 1
except WindowsError as err:
print(err)
pass

(Python3) Using generators and recursivity as i don't like counters...
(Python3) 使用生成器和递归，因为我不喜欢计数器......
def get_keys(self, path, i=0):
try:
yield winreg.EnumValue(winreg.OpenKey(winreg.HKEY_CURRENT_USER, path), i)
yield from get_keys(path, i+1)
except WindowsError as err:
pass
for name, value, type in r.get_keys(r"Local Settings\Software\Microsoft\Windows\Shell\MuiCache"):
print(f"{name} => {value} ({type})"

it seems like this only works on certain key values, for instance i try to run on HKLM:Software\labtech\service there are like 70 different keys and values here, when i run this i only get 3 returns
似乎这只适用于某些键值，例如我尝试在 HKLM:Software\labtech\service 上运行，这里有 70 个不同的键和值，当我运行它时，我只得到 3 个返回

For iterating through keys and values of registry, you would need EnumKey()and EnumValue()method from _winregmodule. Note that these two methods, take index as an argument, and will provide you the key (or value) only for the given index. Therefore, in order to get all the keys (or values) you need to increment the index by one and continue until WindowsErrorhas not encountered.
对于通过按键和注册表的值迭代，你需要EnumKey()和EnumValue()来自法_winreg模块。请注意，这两种方法都将索引作为参数，并且只会为您提供给定索引的键（或值）。因此，为了获得所有键（或值），您需要将索引加一并继续直到WindowsError没有遇到。
