I have a self-made DLL file with two functions: add and sub which take two arguments. add(a, b) returns addition of two numbers sub(a, b) returns substraction of two numbers The name of the DLL file will be "demo.dll" Program: from ctypes import* # give location of dll mydll = cdll.LoadLibrary("C:\\demo.dll") result1= mydll.add(10,1) result2= mydll.sub(10,1) print "Addition value:"+result1 print "Substraction:"+result2 Output: Addition value:11 Substraction:9
