Python comes with a command line for managing user input and specific forms of data entering while Python applications are being executed. As a result, users can enter data and complete tasks otherwise that would be impossible. This also enables more complex tasks and increased program interaction. To communicate with computers and execute programs, one uses a command-line interface (CLI), and a text-based user interface (UI). Additional names for command-line interfaces include character user interfaces, console user interfaces, and command-line user interfaces. In this article, you will learn what the Python command-line interface (CLI) is and how to automate the ... Read More
