What will the value of expiration be for a Medicine object by default, according to its __init__ method?

The value of expiration for a Medicine object by default is often designed to be set in the constructor, or init method, of the class. It is common practice in object-oriented programming for attributes to have default values that are reasonable within the context of the object they represent.

In this case, if the default value for expiration is set to a specific number like 2000 in the init method, that means that when an instance of the Medicine class is created without explicitly providing a value for expiration, it will automatically be assigned the value of 2000. This sets a predictable state for the object and helps prevent situations where an attribute might remain uninitialized or set to None.

By defining such a default value, it ensures that the Medicine object retains useful and accessible information from the outset, which is critical for managing and utilizing such objects effectively in a program.
