How to read input from keyboard instead of file in python

I have the below python snippet

@click.argument('file',type=click.Path(exists=True))

The above command read from a file in the below format

python3 code.py file.txt

The same file is processed using a function

def get_domains(domain_names_file):
    with open(domain_names_file) as f:
        domains = f.readlines()
    return domains
domains = get_domains(file)

I dont want to read it from file , I want to provide a domain as an argument while executing in terminal , the command will be

python3 code.py example.com

How should I rewrite the code .

Python Version : 3.8.2

I realised you're using the click library. Since you want to pass the 'domain'/website as an argument, you can just input it as a string. If you remove the 'type' parameter from your decorator, it would make the type STRING by default.

The most basic option is a simple string argument of one value. If no type is provided, the type of the default value is used, and if no default value is provided, the type is assumed to be STRING.

Solution: @click.argument('domain')

click.argument by default creates arguments that are read from the command line:

@click.argument('file')

This should create an argument that is read from the command line and made available in the file argument.

See the docs & examples here

You may use argparse:

import argparse

# set up the different arguments
parser = argparse.ArgumentParser(description='Some nasty description here.')
parser.add_argument("--domain", help="Domain:   www.some-domain.com", required=True)

args = parser.parse_args()
print(args.domain)

And you invoke it via

python your-python-file.py --domain www.google.com
