1. What is Python? What are the advantages of Python?

Python is a high-level, interpreted, object-oriented programming language known for its simplicity and readability. It is widely used for web development, automation, data science, artificial intelligence, and software development.

Advantages:

• Easy to learn and use
• Cross-platform compatibility
• Open-source
• Rich standard library
• Automatic memory management
• Large developer community

2. What is Pickling and Unpickling?

Pickling is the process of converting a Python object into a byte stream for storage or transmission.

Unpickling is the process of restoring the original Python object from the stored byte stream.

3. What is the Python Interpreter?

The Python Interpreter executes Python code by converting source code into bytecode and then running it through the Python Virtual Machine (PVM).

4. How is Memory Managed in Python?

Python automatically manages memory using a private heap and a built-in garbage collector. It allocates memory for objects and frees unused memory automatically.

5. Which Static Code Analysis Tools are Available in Python?

Popular Python code analysis tools include:

• Pylint
• PyChecker
• Flake8
• MyPy
• Black

These tools help improve code quality and identify potential errors.

6. What are Decorators in Python?

Decorators are special functions used to modify or extend the behavior of another function without changing its original code.

7. What is the Difference Between a List and a Tuple?

A List is mutable, meaning its elements can be modified after creation.

A Tuple is immutable, meaning its elements cannot be changed once created.

8. What are Python Built-in Data Types?

Mutable Data Types

• List
• Dictionary
• Set

Immutable Data Types

• String
• Tuple
• Integer
• Float
• Boolean

9. Does Python Pass Arguments by Value or by Reference?

Python uses Pass-by-Object Reference, where functions receive references to objects rather than copies of values.

10. What is a Namespace in Python?

A Namespace is a container that stores variable names and maps them to objects, helping avoid naming conflicts.

11. What is a Lambda Function?

A Lambda Function is a small anonymous function that can have any number of arguments but only one expression.

12. Why Can’t Lambda Functions Contain Statements?

Lambda functions are designed for single expressions only. They cannot contain statements like loops, assignments, or multiple lines of code.

13. What is Slicing in Python?

Slicing is a technique used to extract a portion of a sequence such as a string, list, or tuple using index ranges.

14. What are Generators in Python?

Generators are special functions that generate values one at a time using the yield keyword, making them memory efficient.

15. What are the Benefits of Learning Python?

• Simple and beginner-friendly syntax
• Fast development
• Large collection of libraries
• Automatic memory management
• Excellent for AI, Machine Learning, Data Science, Web Development, Automation, and Cyber Security
• High demand in the software industry with excellent career opportunities
