Python Tips: How to Retrieve Type of T in Generic[T] Base Class Instances

If you’re working with Python’s generic types, you may need to retrieve the type of T in a Generic[T] base class instance. Here are some common questions people ask about this topic:

• What is a Generic[T] base class instance?
• How do I retrieve the type of T in a Generic[T] base class instance?
• What are some use cases for retrieving the type of T in a Generic[T] base class instance?

1. What is a Generic[T] base class instance?

A Generic[T] base class instance is an instance of a generic class that has a type parameter T. The T parameter can be any type, and is used to define the type of data that will be stored or processed by the class.

2. How do I retrieve the type of T in a Generic[T] base class instance?

You can retrieve the type of T in a Generic[T] base class instance using the __orig_class__ attribute. Here’s an example:

“`python from typing import TypeVar, Generic, List T = TypeVar(‘T’) class MyClass(Generic[T]): def __init__(self, data: List[T]): self.data = data # create an instance of MyClass my_instance = MyClass([‘a’, ‘b’, ‘c’]) # retrieve the type of T t_type = my_instance.__orig_class__.__args__[0] print(t_type) # output: “`

3. What are some use cases for retrieving the type of T in a Generic[T] base class instance?

You may need to retrieve the type of T in a Generic[T] base class instance for several reasons, such as:

• Performing runtime type checks
• Performing type conversions
• Creating new instances of the same type
