How can I integrate user input and command line arguments into my Python scripts?

Utilizing User Input and Command Line Arguments in Python

Inserting user input into Python scripts is essential for creating interactive applications. Additionally, processing arguments provided via the command line when executing the script broadens its functionality. Here's how to achieve both these tasks:

Reading User Input

To acquire user input, consider using the cmd module to establish a basic command line interpreter complete with assistance texts and autocompletion. For a simpler approach, employ the raw_input function (or input in Python 3) to swiftly read in a textual line from the user:

# Python 2
text = raw_input("prompt")

# Python 3
text = input("prompt")

Accessing Command Line Arguments

Parameters supplied through the command line are accessible in the sys.argv list. Incorporate the following code to utilize them:

import sys
print(sys.argv)

Further Enhancements

For enhanced command line parsing, engage the optparse module (deprecated; use argparse instead) or the getopt module. If your script primarily handles file input, the fileinput module offers ample solutions.

Documentation Assistance

The Python Library Reference remains an invaluable resource for further exploration.
