A Python script is a file that contains a series of commands written in the Python programming language. These scripts are used to automate tasks, perform calculations, or manipulate data. By writing a Python script, you can create programs that run on your computer or server, making it easier to handle repetitive tasks without manual effort. Python scripts are popular among developers and data scientists because of their simplicity and readability. They can be executed in various environments, such as IDEs (Integrated Development Environments) or directly in the command line. This flexibility allows users to quickly test and run their code, enhancing productivity.
