游戏存档创建器输出格式异常求助：消除多余空行

我为自研游戏开发了一个存档创建器，但输出不符合预期。预期的game_users.txt格式如下：

default
open
open
open
open
open
open
open
open
open
1

但实际保存的文件部分行之间存在多余空行，尝试多种方法仍无法修复，恳请帮忙解决。

原代码如下：

debug = False

print('Input Save Name')

问题原因分析 #

1. 读取game_users.txt时使用readlines()，每行末尾会保留换行符\n，后续写入时又额外添加\n，导致重复换行出现空行。
2. 构造写入game_users.txt的content列表时，手动添加了空字符串''，写入时会生成多余空行，不符合预期格式。
3. 原text_quality_control函数逻辑冗余，且未彻底处理换行符问题。

修复后的代码 #

debug = False


def profile_creator():
    count2 = 0
    # 用列表替代单独变量，简化结构
    users = ['open'] * 10
    content = ['HS:', '0', 'LS:', '0', 'G:', '0', '', 'LS = Last Score, HS = High Score, G = Games']
    print('> Input Save Name')
    chosen_u = input('>  ').lower()
    
    # 批量写入用户信息文件和备份
    for filename in [f'game_info_{chosen_u}.txt', f'game_info_backup_{chosen_u}.txt']:
        with open(filename, 'w') as f:
            f.write('\n'.join(content))
    
    # 读取并处理game_users.txt，去除换行符
    try:
        with open('game_users.txt', 'r') as f:
            lines = [line.rstrip('\n') for line in f.readlines()]
        # 加载现有用户和计数
        if len(lines) >= 11:
            users = lines[:10]
            count2 = int(lines[10])
    except FileNotFoundError:
        # 文件不存在时初始化默认值
        users = ['default'] + ['open'] * 9
        count2 = 0
    
    # 简化合法字符过滤逻辑
    def text_quality_control(line):
        return ''.join([c for c in line.lower() if c in 'abcdefghijklmnopqrstuvwxyz0123456789'])
    
    # 清理所有用户内容
    users = [text_quality_control(user) for user in users]
    
    count2 += 1
    # 更新对应位置的用户
    if 0 <= count2 - 1 < 10:
        users[count2 - 1] = text_quality_control(chosen_u)
    
    # 构造无多余空行的内容并写入
    content_to_write = users + [str(count2)]
    with open('game_users.txt', 'w') as f:
        f.write('\n'.join(content_to_write))


print('Input Save Name')
profile_creator()

修复说明 #

• 用列表users替代单独的u1到u10变量，简化代码结构。
• 读取文件时用rstrip('\n')去除每行末尾的换行符，避免重复添加导致空行。
• 移除原代码中手动添加的空字符串''，确保写入内容无多余空行。
• 简化text_quality_control函数，用列表推导式过滤合法字符，逻辑更高效简洁。
• 增加文件不存在的异常处理，自动初始化默认存档内容。
• 使用'\n'.join(content)一次性写入所有内容，避免循环中多次写\n的问题。
