About PY Files

A .py file is a text file that contains Python script, a widely-used high-level programming language. Many applications implement Python, from web development and data analysis to machine learning and automation. When a .py script is run, the Python interpreter interprets its code line by line, allowing developers to execute commands and see results quickly.

Guido van Rossum developed Python in 1991 for beginners and experienced developers, emphasizing simplicity and productivity. Over the decades, Python has grown into one of the most popular programming languages with the help of Python's community-driven development, which has led to an extensive library ecosystem, enabling .py files to integrate with various tools and systems. For example, developers use Python across industries for tasks such as building web applications with frameworks like Django or Flask, analyzing data using libraries like Pandas and NumPy, or creating artificial intelligence models with TensorFlow and PyTorch.

Developers often use code editors and integrated development environments (IDEs) when viewing and editing .py files. The programs provide helpful features like syntax highlighting, debugging tools, and autocompletion.
