To rewrite the code using functions and loops effectively, we need to ensure the chatbot() function runs indefinitely until the user inputs ‘quit’. Here’s a structured approach:
-
Function Definition: Define the
chatbot()function which initializes an empty string for user input. -
Infinite Loop: Use a
while True:loop inside the function to continuously prompt the user. -
Input Handling: Inside the loop, use
input()to get the user’s message and trim any extraneous whitespace with.strip(). -
Termination Check: Check if the input is ‘quit’ and break the loop if true.
-
Response Display: Print a welcome message each iteration and handle the response as needed, using predefined responses for clarity.
Here’s the revised code:
def chatbot():
user_input = ""
while True:
print("You: ", end='')
user_input = input().strip()
if user_input == 'quit':
print("\nGoodbye!")
break
else:
print(f"Chatbot: I'm here for you.")
# Call the function to start the chat
chatbot()
This implementation ensures a smooth, interactive session where the user can input messages indefinitely until they choose to exit.
