What is Python and why is it used?

Python is a high-level, interpreted programming language known for its simplicity, readability, and versatility. It emphasizes code clarity and uses indentation rather than complex syntax, making it beginner-friendly while still powerful enough for professionals. 

Python is used for a wide range of applications including web development, data analysis, artificial intelligence, automation, and software testing. Its extensive standard library and thousands of external packages allow developers to handle tasks quickly without writing everything from scratch. Python runs on all major operating systems and integrates easily with other languages like C and Java. 

Its use in data science and machine learning has grown rapidly because libraries such as NumPy, Pandas, TensorFlow, and Scikit-learn simplify complex computations. Developers choose Python for rapid prototyping and scalability, especially in modern tech environments. It is also widely adopted in education due to its low learning curve. In essence, Python is used because it saves time, reduces errors, and supports nearly every major domain in computing—from backend servers to artificial intelligence.
