Main Function Parameters and Reversal in Python

In this exercise, you will develop a Python program named "reverse" that takes multiple words from the command line and prints them in reverse order. This exercise is perfect for practicing command-line input handling and string manipulation in Python. By implementing this program, you will gain hands-on experience in handling command-line input and performing string manipulation in Python. This exercise not only reinforces your understanding of command-line input handling but also helps you develop efficient coding practices for managing user interactions.

Objective

Develop a Python program named "reverse" that takes multiple words from the command line and prints them in reverse order. For example:

reverse one two three three two one

Example Python Exercise

 Copy Python Code 
import sys

# Define the reverse function
def reverse():
    # Get the arguments from the command line (skipping the script name)
    words = sys.argv[1:]
    
    # Reverse the list of words
    reversed_words = words[::-1]
    
    # Print the reversed words
    print(" ".join(reversed_words))

# Main function to run the program
if __name__ == "__main__":
    reverse()

 Output

python reverse.py one two three
three two one
