Core Python:

1. Question: What is Python?
   Answer: Python is a high-level, interpreted programming language known for its simplicity and readability. It offers dynamic typing, automatic memory management, and a wide range of built-in libraries.
2. Question: What are the key features of Python?
   Answer: Key features of Python include easy-to-read syntax, extensive standard library, dynamic typing, automatic memory management, support for multiple programming paradigms (procedural, object-oriented, functional), and cross-platform compatibility.
3. Question: What is PEP 8?
   Answer: PEP 8 is the official style guide for Python code. It provides guidelines on code formatting, naming conventions, and best practices to enhance code readability and maintainability.
4. Question: What are the differences between Python 2 and Python 3?
   Answer: Python 2 and Python 3 have differences in syntax and features. Python 3 introduced improvements like print function as a standard function, better Unicode support, improved syntax for exception handling, and various other enhancements.
5. Question: What are the basic data types in Python?
   Answer: The basic data types in Python are integers, floats, strings, booleans, and None (representing absence of value).
6. Question: Explain the difference between lists and tuples in Python.
   Answer: Lists and tuples are both sequence types, but lists are mutable (can be modified), while tuples are immutable (cannot be modified once created).
7. Question: What is the difference between ‘is’ and ‘==’ in Python?
   Answer: ‘is’ checks if two objects refer to the same memory location, while ‘==’ checks if two objects have the same value.
8. Question: How can you iterate over a sequence in Python?
   Answer: You can iterate over a sequence in Python using loops like ‘for’ and ‘while’.
9. Question: What are the different ways to handle exceptions in Python?
   Answer: Exception handling in Python can be done using ‘try-except’ blocks, where code that may raise an exception is placed in the ‘try’ block, and corresponding exception handling code is placed in the ‘except’ block.
10. Question: Explain the concept of list comprehension in Python.
    Answer: List comprehension is a concise way to create lists based on existing lists or other iterable objects. It combines the ‘for’ loop and conditional statements into a single line of code.

Advanced Python:

1. Question: What are decorators in Python?
   Answer: Decorators are functions that wrap other functions and enhance their behavior. They allow adding functionality to existing functions without modifying their source code directly.
2. Question: Explain the concept of generators in Python.
   Answer: Generators are functions that use the ‘yield’ statement to return values one at a time, allowing iterative processing without storing all the values in memory at once. They are memory-efficient and can be iterated using ‘for’ loops.
3. Question: What is the Global Interpreter Lock (GIL) in Python?
   Answer: The Global Interpreter Lock (GIL) is a mechanism in CPython (the reference implementation of Python) that allows only one thread to execute Python bytecode at a time. It is in place to ensure thread safety.
4. Question: What is the purpose of the ‘with’ statement in Python?
   Answer: The ‘with’ statement is used for context management in Python. It ensures that resources are properly managed and released, even in the presence of exceptions, by automatically calling the ‘enter‘ and ‘exit‘ methods of an object.
5. Question: What are the differences between shallow copy and deep copy?
   Answer: Shallow copy creates a new object that references the original object’s memory, while deep copy creates a new object with a new set of memory, duplicating the original object’s values recursively.
6. Question: Explain the concept of multithreading in Python.
   Answer: Multithreading in Python allows multiple threads to run concurrently within a single process. However, due to the Global Interpreter Lock (GIL), Python threads do not provide true parallelism on multi-core processors.
7. Question: What are the differences between a module and a package in Python?
   Answer: A module is a single file containing Python code, while a package is a collection of modules organized in a directory hierarchy. A package must contain an ‘init.py’ file to be recognized as a package.
8. Question: What is the purpose of the ‘init‘ method in Python classes?
   Answer: The ‘init‘ method is a special method in Python classes that is automatically called when a new object is created. It is used to initialize the object’s attributes.
9. Question: How can you handle file I/O operations in Python?
   Answer: File I/O operations in Python can be performed using built-in functions like ‘open()’, ‘read()’, ‘write()’, and ‘close()’. It is good practice to use the ‘with’ statement for automatic resource management.
10. Question: What is the purpose of the Python standard library?
    Answer: The Python standard library is a collection of modules and packages that provide a wide range of functionalities for tasks such as file operations, networking, data serialization, web development, and more.

I recently completed the Digital Marketing course from ZebLearn and I never felt that course is completed online. The learning environment was so interactive that I felt that I am sitting in the classroom.
