对于循环打印所有步骤，但我只需要最后一个

Question

我正在 python 制作刽子手游戏。现在我陷入了一个问题。我希望 for 循环打印显示

想要的输出：['_', '_', '_', '_', '_']

but it prints:
['_']
['_', '_']
['_', '_', '_']
['_', '_', '_', '_']
['_', '_', '_', '_', '_']

我知道这是 for 循环，但是如何让它只打印我想要的内容？感谢您的宝贵时间和帮助！

import random
word_list = ["aardvark", "baboon", "camel"]
chosen_word = random.choice(word_list)
# Testing code
print(f'Pssst, the solution is {chosen_word}.')
display = []
for letter in chosen_word:
    display.append("_")
print(display)
guess = input("Guess a letter: ").lower()

Answer 1

您似乎缩进了 print(display) 语句并将其添加到 for 循环中。只需取消循环缩进，代码就可以工作了。

import random
word_list = ["aardvark", "baboon", "camel"]
chosen_word = random.choice(word_list)
#Testing code
print(f'Pssst, the solution is {chosen_word}.')
display = []
for letter in chosen_word:
    display.append("_")
print(display)
guess = input("Guess a letter: ").lower()

输出：

Pssst, the solution is aardvark.
['_', '_', '_', '_', '_', '_', '_', '_']
Guess a letter:

Answer 2

我实施这个来练习。当然可以更详细，但作为参考应该有效：

import random

WORD_LIST = ["aardvark", "baboon", "camel"]
MAX_POINTS = 5
chosen_word = random.choice(WORD_LIST)

word = ["".join("_") for i in chosen_word]
print(word)


def guessing():
    # Initial setup
    initial_points = MAX_POINTS
    print(f"initial_points: {initial_points}")

    # store the guess history
    history = set()

    while True:
        if "_" not in word:
            print('you WIN!!')
            break
        elif initial_points < 1:
            print('you LOSE!!')
            break

    guess = input("Guess a letter: ").lower()
    # decrement initial points
    if guess not in chosen_word \
        and guess not in history \
        and guess not in word:
        initial_points -= 1

    for i, c in enumerate(chosen_word):
        if guess == c:
            word[i] = guess

    # Not decrement twice
    history.add(guess)
    
    # display
    print(f"Points: {initial_points} - {word}")
    print(f"Guessed letters: {history}")


guessing()

对于循环打印所有步骤，但我只需要最后一个

For loop printing all steps, but i only need the last

python

loops

for-loop
