This section presents a simple example of how to build a shell around a few of the commands in the turtle module. Basic turtle commands such as forward() are added to a Cmd subclass with method named do_forward(). The argument is converted to a number and dispatched to the turtle module. The docstring is used in the help utility provided by the shell Example: \'show [table name] (access, creds, computers, file servers, pwdpolicy, users) print export Export the contents of the database to a path in one of the following formats: CSV, HTML. (using with -f or --filetype) print exit Exit Vibe return cmd.Cmd.cmdloop(self, intro) Example 16

To see how to apply the first method in practice, let's review a simple example where we'll execute a simple command in Python to: Display the current date in the Command Prompt; The Command Prompt will remain opened following the execution of the command; You may then apply the following code in Python to achieve the above goals: import os os.system('cmd /k date') Once you run the code in Python, you'll get the. Basics in Command Line Interface with Python Now lets take a little peek at command line interface and building one in Python. A command-line interface (CLI) usually starts with the name of the executable. You just enter it's name in the console and you access the main entry point of the script, an example is pip For example, if you have defined a color command, the completion method for this command could be: _AVAILABLE_COLORS = ('blue', 'green', 'yellow', 'red', 'black') def complete_color(self, text, line, begidx, endidx): return [i for i in _AVAILABLE_COLORS if i.startswith(text)
