Python ctypes.WinDLL error , _dlopen(self._name, mode) can't be found
提问by wizztjh
ctypes.WinDLL("C:\Program Files\AHSDK\bin\ahscript.dll")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python26\lib\ctypes\__init__.py", line 353, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found
How can I solve it? I found the _dlopen in C:\Python26\lib\ctypes\__init__.py, but I really don't know how to solve it.
我该如何解决？我在 中找到了 _dlopen C:\Python26\lib\ctypes\__init__.py，但我真的不知道如何解决它。

Backslashes are an escape character within strings, as demonstrated in the example below:
反斜杠是字符串中的转义字符，如下例所示：
>>> print "C:\Program Files\AHSDK\bin\ahscript.dll"
C:\Program Files\AHSDinhscript.dll
You can solve the problem by placing an r before the string, which prevents the backslash from working as an escape character:
您可以通过在字符串前放置一个 r 来解决这个问题，这可以防止反斜杠作为转义字符工作：
ctypes.WinDLL(r"C:\Program Files\AHSDK\bin\ahscript.dll")
Alternately, you could escape the backslashes:
或者，您可以逃避反斜杠：
ctypes.WinDLL("C:\Program Files\AHSDK\bin\ahscript.dll")
