In Python scientific computing, how do I build a CLI?

In Python scientific computing, building a Command Line Interface (CLI) can be accomplished using various libraries like `argparse`, `click`, or `fire`. These libraries help you create user-friendly command-line tools that can take input parameters and execute scientific computations efficiently.

Example of Building a CLI using argparse

import argparse

def main(args):
    # Example function to perform a computation
    result = args.number ** 2
    print(f"The square of {args.number} is {result}")

if __name__ == "__main__":
    parser = argparse.ArgumentParser(description='A simple CLI for scientific computing.')
    parser.add_argument('number', type=int, help='An integer number to be squared.')
    args = parser.parse_args()
    main(args)
