   If a class only contains fixed (or predetermined) instance attributes, you can use the slots to instruct Python to use a more compact data structure instead of dictionaries. For example, if the Point2D class has only two instance attributes, you can specify the attributes in the slots like this:

   What is __slots__ in Python?

   • This allows you to dynamically add more attributes to instances at runtime but also create a memory overhead. Define __slots__ in the class if it has predetermined instances attributes to instruct Python not to use dictionaries to store instance attributes. The __slots__ optimizes the memory if the class has many objects.

   How fast is __slots__ in Python?

   • The slotted access is almost 30% faster in Python 3.5 on Ubuntu. In Python 2 on Windows I have measured it about 15% faster. Another purpose of __slots__ is to reduce the space in memory that each object instance takes up. My own contribution to the documentation clearly states the reasons behind this:
