关于字节序列化和反字节序列化的方法__bytes__和fromBytes几乎和Vector中的没有区别,只不过在反字节序列化的时候,return cls(arrayVectorN)没有使用*,这是因为我们在第一点中所说的,现在初始化方法只接收一个可迭代对象。 使用property装饰器的目的和之前一样,是为了后续实现散列。 现在我们简单测试一下: from ...

它的实现和 C++ 中的std::vector类似,都是通过维护一个动态数组,在增加数据的时候动态扩大数组的容量来实现的;PyListObject结构中包含了一个变长对象头部PyObject_VAR_HEAD,ob_size表示当前动态数组的长度,**ob_item是指向动态数组的指针,allocated是动态数组的容量;我们可以从它的类型指针PyTypeObject PyList_Type...

1. 与3d相关的一些python module 例如the vector, matrix and quaternion types, the RenderMan bindings, noise functions 这些模块可以在maya houdini nuke blender 等有Python扩展的程序中直接用; 2. 提供完整的场景操作的module, 他类似其他三维软件,在内存中保留完整的描述场景的信息。
假设当前文件夹中有个内含Vector3.py文件的testZip.zip文件,首先导入sys模块,然后执行sys.path.append(‘testZip.zip’),然后即可导入Vector3.py文件作为模块来使用。 >>> import sys >>> sys.path.append('testZip.zip') >>> import Vector3 >>> Vector3.__file__ #查看已导入模块对应的程序文件 '...
__module__: 类定义所在的模块(类的全名是'__main__.className',如果类位于一个导入模块mymod中,那么className.__module__ 等于 mymod) __bases__ : 类的所有父类构成元素(包含了以个由所有父类组成的元组) Python内置类属性调用实例如下: 代码语言:javascript ...
For example, the NumPy package also has linalg sub-module that has a solve function. However, the NumPy solve function has no optional parameters. Next, the demo program shows an example of the Python try-except mechanism: XML Copy try: A = np.array([[2.0, 4.0], [3.0, 6.0]])...
