How can I perform data validation in Python?

You can perform data validation in Python using libraries like Pandas, Pydantic, or by writing custom validation functions.

What is Pydantic and how does it help with data validation?

Pydantic is a data validation and settings management library that uses Python type annotations to validate data structures.

Can you show me a simple example of using Pydantic?

Sure! Here's a basic example:

from pydantic import BaseModel

class User(BaseModel):
    name: str
    age: int

user = User(name='Alice', age=30)
print(user)

What if the data doesn't match the expected types?

Pydantic will raise a ValidationError if the data types do not match the expected types, helping you catch errors early.
