How do you interact with your Python scripts: User input or command-line arguments?

Leveraging User Input and Command Line Arguments in Python

When it comes to user interaction, Python offers two primary options: reading user input and processing command line arguments. Let's explore these capabilities.

Reading User Input

Python provides several methods for gathering user input, including the cmd module and the raw_input and input functions. The raw_input function (or input in Python 3 ) enables you to read a line of text from the user.

For example:

text = raw_input("Enter your name: ")  # Python 2
text = input("Enter your name: ")  # Python 3

Processing Command Line Arguments

Command line arguments can be accessed through the sys.argv list. The first argument is always the script name, followed by the user-provided arguments.

Here's how you can print the command line inputs:

import sys
print (sys.argv)

Additional Modules

For more advanced handling of command line options, consider using the argparse module. This module allows you to define command line arguments with types, help texts, and default values.

Conclusion

By leveraging user input and command line arguments, you can create interactive Python scripts that respond to user commands and accept parameters from the command line. These capabilities enhance user interaction and streamline script execution.
