How do I validate dicts in Python with type hints?

In Python, you can validate dictionaries using type hints by leveraging the `TypedDict` from the `typing` module. This allows you to specify the expected structure of the dictionary, including the types of its keys and values. Below is a simple example demonstrating how to create and validate a dictionary using type hints.

from typing import TypedDict class User(TypedDict): name: str age: int email: str def validate_user(user: User) -> None: print(f"Name: {user['name']}") print(f"Age: {user['age']}") print(f"Email: {user['email']}") # Example usage user_data: User = {'name': 'John Doe', 'age': 30, 'email': 'john.doe@example.com'} validate_user(user_data)
