Python实现持续获取用户输入直至输入no并输出CSV及打印响应

Got it, here's a practical, easy-to-follow implementation that does exactly what you need—collects user input until they type "no", prints all responses to the console, and saves everything to a CSV file. Let's walk through it:

How It Works #

• We'll use a loop to keep asking for input until the user enters "no" (case-insensitive, so "No" or "NO" works too)
• We'll store valid inputs in a list (ignoring empty entries to keep things clean)
• After input stops, we'll print all collected responses with numbered entries
• Finally, we'll write the data to a CSV file with a clear header for readability

Full Code Implementation #

import csv

# Initialize an empty list to store user's valid inputs
user_responses = []

print("Start entering your text (type 'no' when you're done):")

while True:
    # Get input and trim any leading/trailing whitespace
    current_input = input("> ").strip()
    
    # Check if user wants to exit the loop
    if current_input.lower() == "no":
        break
    
    # Only add non-empty inputs to our list
    if current_input:
        user_responses.append(current_input)
    else:
        print("Oops, empty input! Please enter some text or 'no' to stop.")

# Print all collected responses to the console
print("\n--- All Collected Responses ---")
for count, response in enumerate(user_responses, start=1):
    print(f"{count}. {response}")

# Write the responses to a CSV file
if user_responses:
    # Use newline="" to avoid extra blank lines in CSV on Windows
    with open("user_responses.csv", "w", newline="", encoding="utf-8") as csv_file:
        csv_writer = csv.writer(csv_file)
        # Write a header row for clarity
        csv_writer.writerow(["Response ID", "Response Text"])
        # Write each response as a separate row
        for count, response in enumerate(user_responses, start=1):
            csv_writer.writerow([count, response])
    print("\n✅ Responses saved to user_responses.csv successfully!")
else:
    print("\nℹ️ No valid responses collected, so no CSV file was created.")

Key Details to Note #

• Case Insensitivity: Using current_input.lower() ensures the exit condition works regardless of how the user capitalizes "no"
• Empty Input Handling: We skip blank entries so your CSV doesn't have unnecessary empty rows
• UTF-8 Encoding: This ensures special characters (like accents or emojis) are saved correctly in the CSV
• Clean Console Output: Numbered responses make it easy to review what was entered

Alternative: Simplified CSV (No Header/ID) #

If you prefer a simpler CSV with just one column of responses (no headers or IDs), replace the CSV writing section with this:

if user_responses:
    with open("user_responses.csv", "w", newline="", encoding="utf-8") as csv_file:
        csv_writer = csv.writer(csv_file)
        for response in user_responses:
            csv_writer.writerow([response])
    print("\n✅ Responses saved to user_responses.csv successfully!")
