Python调用C++的dll

一、Python代码

第一种加载动态库的写法，自己写的取路径

import ctypes , ctypes.util
def find_dll(dll_name):
     return ctypes.util.find_library(dll_name)#查找dll

def load_dll(dll_path):
    try:
        print("第一步")
    except OSError as e:
        print(e,"加载失败")

if __name__ == '__main__':
    dll_path = find_dll("mousedll.dll")
    if dll_path:
        load_dll(dll_path)
        print("第2步，加载dll成功")
        vc_dll = ctypes.CDLL(dll_path)  # 加载动态库，若失败抛出一场
        vc_func = vc_dll.Add(2, 3
