Introduction to Python
Python का परिचय
What is Python?
Python is a high-level, interpreted programming language. It is popular because its syntax is simple, readable and close to English. Python is used in web development, automation, data analysis, machine learning, artificial intelligence, scripting and education.
Main Features of Python
| Feature | Meaning |
|---|---|
| Simple Syntax | Python code is easy to read and write. |
| Interpreted | Python runs code line by line, so testing is easier. |
| High-level | You focus on logic, not hardware details. |
| Large Libraries | Python has libraries for web, data science, AI, automation and more. |
| Cross-platform | Python works on Windows, macOS and Linux. |
Where is Python used?
- Web development using Django/Flask/FastAPI.
- Automation scripts for files, emails and reports.
- Data analysis using pandas and NumPy.
- Machine learning and AI using scikit-learn, TensorFlow and PyTorch.
- Desktop tools, APIs, web scraping and testing.
First Python Example
print("Python is easy to read")
print("Python is used in web, data science, ML and AI")
print("10 + 20 =", 10 + 20)Expected Output
Summary
Python is a beginner-friendly but powerful language. Start with syntax, variables, operators, input/output and conditions; then move to functions, files, OOP, data science and AI.
