Here are commonly asked Python interview questions for freshers along with their answers:

1. What is Python?
   • Python is a high-level, interpreted, general-purpose programming language.
   • It is widely used to build various types of applications due to its simple syntax and flexibility.
   • Key features include support for objects, modules, threads, exception handling, and automatic memory management.
2. What are the benefits of using Python?
   • Readability: Python emphasizes readability, reducing program maintenance costs.
   • Open Source: Python is open-source and supports third-party packages, encouraging modularity and code reuse.
   • Dynamic Typing: Python’s dynamic typing allows for rapid development and flexibility.
   • High-Level Data Structures: Python provides high-level data structures and dynamic binding.
   • General-Purpose: Python can be used for a wide range of applications.
3. Is Python a compiled or interpreted language?
   • Python is an interpreted language. It is executed line by line, rather than being compiled into machine code beforehand.
4. What is PEP 8, and why is it important?
   • PEP 8 (Python Enhancement Proposal 8) is a style guide for writing Python code.
   • It promotes consistent and readable code by defining conventions for indentation, naming, and other aspects.
5. What is scope in Python?
   • Scope refers to the region where a variable is accessible.
   • Python has local, enclosing, global, and built-in scopes.
6. What are lists and tuples? What’s the key difference?
   • Both are sequence types in Python.
   • Lists are mutable (can be modified), while tuples are immutable (cannot be changed after creation).
7. What are the common built-in data types in Python?
   • Common data types include Integers,
   • Floats,
   • String,
   • Lists,
   • Tuples,
   • Dictionaries and Sets
8. What is the difference between a list and a tuple in Python?
   • Lists are mutable (can be modified), while tuples are immutable (cannot be changed after creation).
   • Lists use square brackets ([]), while tuples use parentheses (()).
9. What are decorators in Python?
   • Decorators are functions that modify or enhance other functions or methods.
   • They are often used for tasks like logging, timing, or adding functionality to existing code.
10. How does memory management work in Python?
    • Python uses a private heap space to manage memory.
    • The memory manager allocates and deallocates memory for objects automatically.
