python 操作HighScore Plus

HighScore Plus是一个假设的游戏高分插件或工具，它通常用于保存并管理游戏中的最高分数或其他成就数据。在Python中操作HighScore Plus可能会涉及到以下几个步骤：

1. **导入库**：如果你使用的是文本文件存储数据，你可以导入`json`库来进行读写操作。如果需要持久化存储，可能会用到`sqlite3`库。

import json
# 或者
import sqlite3

2. **创建或打开数据库**（如果使用SQLite）：

conn = sqlite3.connect('highscores.db')
c = conn.cursor()

3. **添加新记录**：

def add_high_score(player_name, score):
    # 对于json:
    with open('highscores.json', 'w') as f:
        high_scores = json.load(f) if f.exists() else []
        high_scores.append({'player': player_name, 'score': score})
        json.dump(high_scores, f)

    # 对于SQLite:
    c.execute("INSERT INTO highscores (player, score) VALUES (?, ?)", (player_name, score))
    conn.commit()

4. **查询最高分**：

def get_top_score():
    # json:
    with open('highscores.json') as f:
        high_scores = json.load(f)
        return max(high_scores, key=lambda x: x['score'])['score']

    # SQLite:
    c.execute("SELECT MAX(score) FROM highscores")
    top_score = c.fetchone()[0]
    return top_score

5. **更新或删除记录**：

def update_score(player_name, new_score):
    # 更新json:
    high_scores = json.load(open('highscores.json'))
    for i, entry in enumerate(high_scores):
        if entry['player'] == player_name:
            high_scores[i]['score'] = new_score
            break
    json.dump(high_scores, open('highscores.json', 'w'))

    # 更新SQLite:
    c.execute("UPDATE highscores SET score=? WHERE player=?", (new_score, player_name))
    conn.commit()

def delete_score(player_name):
    # 删除json:
    high_scores = json.load(open('highscores.json'))
    high_scores = [entry for entry in high_scores if entry['player'] != player_name]
    json.dump(high_scores, open('highscores.json', 'w'))

    # 删除SQLite:
    c.execute("DELETE FROM highscores WHERE player=?", (player_name,))
    conn.commit()
