v->push_back(i);
}
}

编译： gcc -fPIC -shared -lpython3.6m -o vector_py.so vectory_py.c

编写 ctypes 类型文件

from ctypes import *
class c_point_t(Structure):
 _fields_ = [("x", c_int), ("y", c_int)]
class Vector(object):
 lib = cdll.LoadLibrary('./vector_py_lib.so') # class level loading lib
 lib.new_vector.restype = c_void_p
 lib.new_vector.argtypes = []
 lib.delete_vector.restype = None
 lib.delete_vector.argtypes = [c_void_p]
 lib.vector_size.restype = c_int
 lib.vector_size.argtypes = [c_void_p]
 lib.vector_get.restype = c_point_t
 lib.vector_get.argtypes = [c_void_p, c_int]
 lib.vector_push_back.restype = None
 lib.vector_push_back.argtypes = [c_void_p, c_point_t]
