2. What are the advantages of using Python?

Python is an open source language, meaning it is free to use and modify for any purpose. It is also easy to learn and use, so you'll be up and running quickly. It has a large community of developers and users, so you can find help and resources easily. It is also highly extensible, meaning it is easy to add new features and tools.

Python 2 and Python 3 are two different versions of the Python programming language. Python 2 was first released in 2000, while Python 3 was released in 2008. Python 3 is the current version and is recommended for beginners. It has many improved features, such as better Unicode support and improved performance.

4. What is the PEP 8 style guide?

The PEP 8 style guide is an official Python style guide that sets standards for writing Python code. It helps ensure consistency and readability across code bases. It is a must-read for all Python developers.

5. What is the difference between list and tuple?

A list is an ordered collection of objects that can be changed, while a tuple is an immutable collection of objects that cannot be changed once created. A list is denoted by square brackets ([]) and a tuple is denoted by parentheses (()).

6. What is the difference between a list and an array?

An array is a data structure used to store multiple values of the same type, while a list is a collection of objects of any type. Arrays are more efficient than lists, because they are more space-efficient and have faster access times.

7. How do you create a dictionary in Python?

A dictionary is a data structure that stores key-value pairs. To create a dictionary, use curly brackets ({}) and a colon (:) to separate the key and value. For example, {"name": "John"} creates a dictionary with the key "name" and the value "John".

8. What are comments in Python?

Comments are used to add explanatory notes to your code. They are ignored by the Python interpreter and are written in plain English. Comments start with a # symbol.

9. What is a lambda function?

A lambda function is an anonymous function (one without a name) used to perform a single operation. They are often used in short snippets of code to perform a simple task.

10. What is the purpose of the else statement in a try-except block?

The else statement is used to execute code if no errors are encountered in the try block. This ensures that the try block code is executed regardless of whether or not an error is encountered.

11. What is the difference between break and continue?

The break statement is used to break out of a loop, while the continue statement is used to skip the current iteration of the loop and move on to the next one.

12. What are the differences between a list and a set?

A list is an ordered collection of objects, while a set is an unordered collection of unique objects. A list allows duplicate elements, while a set does not.

13. What is the difference between a shallow copy and a deep copy?

A shallow copy creates a new object but does not create copies of the objects within the original object, while a deep copy creates a new object and also creates copies of the objects within the original object.

14. What is the difference between strings and tuples?

Strings are immutable, while tuples are mutable. Strings are written in double or single-quotes, while tuples are written in parentheses.

15. What are the four main data types in Python?

The four main data types in Python are strings, integers, floats, and Booleans.

16. What is a decorator in Python?

A decorator is a function or class that takes another function as an argument and adds some additional functionality to it. Decorators are used to modify the behavior of a function without changing its definition.

17. What are the different types of inheritance supported by Python?

Python supports single inheritance, multiple inheritance, and multilevel inheritance.

18. How does garbage collection work in Python?

Garbage collection in Python is handled by the reference counting mechanism. It keeps track of the number of references to an object in memory and deletes the object when the reference count reaches zero.

19. What is the purpose of the is keyword in Python?

The is keyword is used to test if two variables refer to the same object.

20. What is an exception in Python?

An exception is an error that occurs during the execution of a program. Exceptions can be handled using try-except blocks in Python.
