Python入门：Hangman猜字游戏已猜字母未保留显示问题求助

Hey there! Congrats on diving into Python projects after just a week—Hangman is a great (and tricky) choice. Let's fix that "correct letters not staying visible" issue first, then I'll share some tips to make your Stack Overflow questions even more effective.

First: Fixing the Letter Persistence Problem #

The main issue is your code isn't tracking all previously guessed letters—right now it only checks the current input each time. Here's how to adjust it, plus fix a few other small bugs:

Modified Working Code #

import random

name = input("Please enter your name to play Hangman! ")
print(f"Welcome {name}! Let's play Hangman.")
# Set default to 6 if user doesn't enter a valid number (optional but user-friendly)
try:
    wrong_attempt = int(input("How many incorrect attempts do you want? "))
except ValueError:
    wrong_attempt = 6
    print("Using default 6 attempts.")

# Read the secret word and remove any extra newline/whitespace
with open('words.csv', "r") as f:
    secret_word = f.readline().strip()

# Initialize display with asterisks for each letter in the secret word
display = ['*'] * len(secret_word)
guessed_letters = set()  # Track all guessed letters to avoid repeats

while wrong_attempt > 0:
    # Print current progress first
    print("\nCurrent word: " + ''.join(display))
    
    letter = input("Guess a letter: ").lower()  # Make input case-insensitive
    
    # Handle repeated guesses
    if letter in guessed_letters:
        print(f"You already guessed '{letter}'! Try another one.")
        continue
    guessed_letters.add(letter)
    
    # Check if the letter is in the secret word
    if letter in secret_word:
        # Update display to show the correct letter(s)
        for idx, char in enumerate(secret_word):
            if char == letter:
                display[idx] = letter
        # Check if user has won
        if '*' not in display:
            print(f"\nCongratulations {name}! You won! The word was {secret_word}")
            break
    else:
        wrong_attempt -= 1
        print(f"Bad luck! That's not in the word. You have {wrong_attempt} attempts left.")

# If loop ends because no attempts left
else:
    print(f"\nGame over! You lose. The secret word was {secret_word}")

Key Changes Explained: #

• Tracking Correct Letters: We use a display list to hold asterisks and replace them with correct letters as they're guessed—this keeps your progress visible between turns.
• Avoid Repeats: A guessed_letters set stops users from guessing the same letter twice (no need to penalize them for that!).
• Win Condition: We check if there are no more asterisks in display—if so, the user wins and the game ends early.
• Input Handling: Added case-insensitivity (so 'C' and 'c' count the same) and a fallback for invalid attempt numbers.
• Clean Word Reading: strip() removes any extra newline characters from the CSV file, so your secret word doesn't have hidden whitespace.

Tips for Asking Great Stack Overflow Questions #

Since you're new to asking on SO, here are some quick pointers to get better, faster answers:

• Write a Clear Title: Instead of something vague like "Hangman game problem", use specific language like "Python Hangman: Correctly guessed letters don't persist between guesses".
• Show Exact Expected vs. Actual Output: For example: "When I guess 'c' then 'o', I expect to see 'co****', but I get 'o***' instead." This helps others immediately understand the issue.
• Include Minimal, Reproducible Code: Your original code was great because it's complete—but if your words.csv has a specific format (like one word per line), mention that so others can replicate your setup easily.
• State What You've Tried: Mention that you tried using a guesses variable but weren't sure how to implement it—this shows you've put in effort and helps others avoid repeating what you already know.
• Format Your Code Properly: You already used code blocks, which is perfect! Never paste unformatted code—it's hard to read.
