Python調用C++的DLL

import os
import sys
from ctypes import *

test = cdll.LoadLibrary('D:\Python27\py.dll')
print test.Add(1, 2)
test.Echo("hello dll")

mypath = sys.argv[1]
if not os.path.exists(mypath):
    print "The path %s does not exist!" % mypath
    sys.exit(2)

for f in [s for s in os.listdir(mypath) if os.path.splitext(s)[1] == ".csta"]:
    outputname = f + ".csv"
    test.Analyzer(os.path.join(mypath,f), os.path.join(mypath,outputname))
    print "%s >> %s" %(f, outputname)

程序思路：

　　1. 調用cdll.LoadLibrary將dll導入進來；

　　2. 32bit的dll在64bit的Python中無法使用；
