A lightweight Python chatbot that responds to messages using exact or close matches with difflib.

DecoderBot is a simple Python class that lets you build a chatbot that replies to input messages based on:

• Exact matches (like "hello")
• Closest matches (like "helo" → "hello"), if difflib is available

No extra libraries. No nonsense. Just logic.

• 🧠 Exact and fuzzy response matching
• 🛠️ Add or update responses easily
• 📦 Zero external dependencies
• 🔥 Lightweight and fast

from DecoderBot import ChatBot

bot = ChatBot("Your Bot Name")

# Add a custom response
bot.train_for("yo", "What's up?")

# Get exact match response
print(bot.get_response("yo"))  # Output: What's up?

# Get a close match response (e.g. "helo" → "hello")
try:
    print(bot.get_closest_response("helo"))
except Exception as e:
    print(e)
