Python 使用 space 键从输入继续

Question

我正在制作一个打字速度测试游戏，并试图让它在用户输入 python input() 时，可以由他们按 space 而不是提交不仅仅是在 Windows 上输入。我的代码类似于以下内容：

score = 0
start_time = int(time.time())
characters = 0
words = 0
current_word = random.choice(WORDS)
next_word = random.choice(WORDS)
while (int(time.time()) - start_time) <= TIME_LIMIT:
    os.system('cls')
    print(f"Your word is {current_word}")
    print(f"The next word will be {next_word}")
    print(f"Your current score is {score}")
    attempt = input("> ")
    if attempt.lower() == current_word.lower():
        score = score + 1
        words = words + 1
        characters = characters + len(current_word)
    current_word = next_word
    next_word = random.choice(WORDS)

有什么方法可以让它工作，还是最好创建我自己的输入函数？

Answer 1

通过创建我自己的输入函数解决了这个问题，如下所示：

def custom_input(prefix=""):
    """Custom string input that submits with space rather than enter"""
    concatenated_string = ""
    sys.stdout.write(prefix)
    sys.stdout.flush()
    while True:
        key = ord(getch())
        # If the key is enter or space
        if key == 32 or key == 13:
            break
        concatenated_string = concatenated_string + chr(key)
        # Print the characters as they're entered
        sys.stdout.write(chr(key))
        sys.stdout.flush()
    return concatenated_string

Answer 2

以下代码根据@gandi给出的答案How to code autocompletion in python?修改而来

它可以实时获取用户的输入。 Backspace 将光标向后移动一个字符。

    old = termios.tcgetattr(fd)
    new = termios.tcgetattr(fd)
    new[3] = new[3] & ~termios.ICANON & ~termios.ECHO

    termios.tcsetattr(fd, termios.TCSANOW, new)
    c = None
    try:

    if c == b'\x7f': # Backspace/delete is hit
        return "delete"
    return c.decode("utf-8")

        else:
