Building a Command-Line Interface with Python
Python is a powerful scripting language that is well-suited for building command-line interfaces (CLI). In this post, we will explain how to build a CLI using Python. Using the argparse Module The argparse module, part of Python's standard library, makes it easy to build a CLI. It allows you to parse and handle command-line arguments. Let's take a look at an example of building a simple CLI. In this example, we have a simple program that adds two numbers entered by the user. First, import the argparse module: import argparse Next, create an ArgumentParser object and add arguments to it: parser = argparse.ArgumentParser(description='Add two numbers.') parser.add_argument('num1', type=int, help='First number') parser.add_argument('num2', type=int, help='Second number') Now, parse the command-line arguments and perform the addition: args = parser.parse_args() result = args.num1 + args.num2 Finally, print the re...
