Python is a dynamic, high-level, and free open-source programming language. It supports both object-oriented and procedural-oriented programming paradigms.
Key characteristics:
Interpreted: Python code is executed line by line without the need for compilation.
Dynamically typed: Variables don’t require explicit type declarations.
Readable and expressive syntax: Python emphasizes code readability through significant indentation.
Large community support: Python has an active community on platforms like Stack Overflow.
Extensive libraries: Python offers a rich ecosystem of libraries and frameworks.
2.How to Install Python?
Python can be installed on various platforms:
Windows: You can download the official installer from the Python website.
macOS: Use the official installer or install via package managers like Homebrew.
Linux: Install using package managers specific to your distribution (e.g., apt-get for Ubuntu).
3.What are the key features of Python?
Easy to code: Python’s simple syntax makes it beginner-friendly.
Object-Oriented: Supports classes, encapsulation, and inheritance.
GUI Programming: Libraries like Tkinter, PyQt, and Kivy enable GUI development.
High-level language: Abstracts system architecture and memory management.
Large community support: Active community on platforms like Stack Overflow.
Easy to debug: Clear error traces aid in identifying issues.
Portable: Code written for one platform can run on others.
Integrated: Easily integrates with other languages (e.g., C, C++).
Interpreted: No need for compilation.
Readability: Python’s straightforward syntax enhances readability.
4.What are the applications of Python?
Web Development: Python is widely used for building websites using frameworks like Django and Flask.
AI and Machine Learning: Python is the go-to language for data analysis, ML models, and AI applications.
Game Development: Pygame and other libraries facilitate game creation.
Desktop GUI Development: Tkinter, WxPython, and others support GUI applications.
Enterprise/Business Applications: Python is used for business management software (e.g., Odoo).
Software Development: Python aids in building, testing, and managing software.
Educational Purposes: Its simplicity makes it ideal for beginners.
5.What is a dynamically typed language?
In Python, variables don’t require explicit type declarations. Their type is determined at runtime based on the assigned value.
6.Difference between list and tuples in Python:
Lists:
Mutable (can be modified after creation).
Denoted by square brackets ([]).
Supports operations like append, remove, and sort.
Tuples:
Immutable (cannot be modified after creation).
Denoted by parentheses (()).
Used for fixed data that shouldn’t change.
7.What are Pickling and Unpickling?
Pickling: Serialization process to convert Python objects into a byte stream (usually for storage or transmission).
Unpickling: Deserialization process to reconstruct Python objects from the byte stream.
