Answer 1

Backslashes are an escape character within strings, as demonstrated in the example below:

>>> 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:

ctypes.WinDLL(r"C:\Program Files\AHSDK\bin\ahscript.dll")

Alternately, you could escape the backslashes:

ctypes.WinDLL("C:\\Program Files\\AHSDK\\bin\\ahscript.dll")
