   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 the slots constant variable work in Python?

   • This article will discuss how the slots constant variable work in Python and how it is any better than using dictionaries. Slots is a concept of memory optimization on objects that would improve our Python code runtime. For example, when we create a custom object from a class, the attributes of the stored object in a dictionary are called __dict__.

   Why is __slots__ a problem in Python?

   • Notice that when calling the __slots__ variable, we only access the keys to map each value in a dictionary. Although Python’s dictionary is incredibly intuitive, there may be problems if we try to create thousands or millions of items simultaneously. Dictionary needs memory. Millions of objects will eat up the RAM usage.

   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:

   __slots__ is a special attribute in Python that allows a programmer to specify which attributes can be assigned to an instance of a class. It is used to reduce the memory overhead of creating instances, as it allows the interpreter to store the instance variables in a more memory-efficient way.
