[jenyyy4]

Description

This PR introduces a command-line Text-to-Morse Code Converter built in Python. It allows users to convert plain text into standardized Morse code directly from the terminal.

Features

• Converts any text input into Morse code (A–Z, 0–9, and common punctuation)
• Supports input from text strings or files
• Handles unknown characters gracefully with a configurable placeholder
• Option to remove or include / separators between words
• Simple, dependency-free implementation (no external libraries required)
• Clean CLI interface using Python’s argparse

To Run:

python3 morse_converter.py --text "Hello World"

Output for "Hello World": .... . .-.. .-.. --- / .-- --- .-. .-.. -..
