10 Frequently Asked Questions (FAQs):

1. Q: What is polymorphism in Python?
   • A: Polymorphism allows methods to have the same name but behave differently based on the object they are called on.
2. Q: How do decorators enhance functions in Python?
   • A: Decorators allow for the modification or enhancement of functions without changing their actual code.
3. Q: What is the difference between lists and tuples in Python?
   • A: Lists are mutable (can be changed), while tuples are immutable (cannot be changed).
4. Q: Can you explain the concept of a RESTful API?
   • A: RESTful APIs are web services that use HTTP requests to perform CRUD operations (Create, Read, Update, Delete) on resources represented in formats like JSON.
5. Q: What is the purpose of unit testing in Python?
   • A: Unit testing involves testing individual components of a program to ensure each part functions correctly.
6. Q: How does Python implement inheritance?
   • A: Inheritance in Python allows one class (child class) to inherit attributes and methods from another class (parent class).
7. Q: What are generators in Python, and how are they useful?
   • A: Generators are a type of iterable that generate items on the fly, which is more memory-efficient than storing a complete list.
8. Q: What is a DataFrame in Pandas?
   • A: A DataFrame is a two-dimensional, size-mutable, and potentially heterogeneous tabular data structure in Pandas.
9. Q: How is TensorFlow different from Scikit-learn in machine learning?
   • A: TensorFlow is more focused on deep learning algorithms, while Scikit-learn provides a range of traditional machine learning algorithms.
10. Q: What is the significance of metaclasses in Python?
    • A: Metaclasses in Python are a class of a class that defines how a class behaves. They are advanced features used to control class creation.
