A Python script is a file containing a sequence of instructions written in the Python programming language. These scripts are used to automate tasks, perform calculations, or manipulate data. They can be executed directly by the Python interpreter, making it easy to run and test code quickly. Python scripts are commonly used in various fields, including web development, data analysis, and artificial intelligence. They can be simple, performing basic tasks, or complex, integrating with other software and systems. The versatility of Python allows developers to create scripts that can solve a wide range of problems efficiently.
