This article illustrates the method of Python calling the DLL dynamic-link library with examples as follows: Example one: First, in creating a DLL project (this example creates an environment of VS 2005), the header file: Hello.h #ifdef export_hello_dll #define HELLO_API __declspec (dllexport) #else #define HELLO_API _ _declspec (dllimport) #endif extern "C" { hello_api int intadd (int, int);

%s called [%s]."% (func.__name__, arg)) return __deco return _decodef myfunc (): Print ("MyFunc () called.") def myfunc1 (): Print ("MyFunc () called.") MyFunc = Deco () (myfunc) myfunc1 = Deco ("Haha1") (MYFUNC1)Then look at the use of wraps in standard library functools, such as the official website example:From Functools import Wrapsdef my_decorator (f): @wraps (f) def wrapper (*args, **kwds): print ' calling decorate D function ' return F (*args,

The import statement in Python imports a library file path that can be viewed through sys.path. Write a simple applet:1 Import SYS 2 Print Sys.pathTo run it, the results on this machine are as follows:[', '/usr/local/lib/python2.7/dist-packages/paste-1.7.5.1-py2.7.egg ', '/usr/lib/python2.7 ', '/usr/lib/python2.7/ Plat-x86_64-linux-gnu ', '/usr/lib/python2.7/lib-tk ', '/usr/lib/python2.7/lib-old ', '/usr/li
