如何用Python将Pokemon Top Trumps游戏分数写入文件并读取？

要实现分数的写入和读取，我们可以通过Python的文件操作完成，分为读取历史分数和保存当前游戏分数两个核心步骤，以下是具体实现：

一、核心逻辑说明 #

1. 读取历史分数：游戏启动时尝试从文件（比如pokemon_scores.txt）读取之前的分数记录，若文件不存在则初始化记录。
2. 保存当前分数：当玩家选择结束游戏时，将本次游戏的玩家名称、玩家分数、对手分数写入文件，可选择追加记录或覆盖最新记录。

二、修改后的完整代码 #

import random
import requests

# 定义获取随机宝可梦的函数（移到循环外，避免重复定义）
def random_pokemon():
    pokemon_number = random.randint(1, 151)
    url = f'https://pokeapi.co/api/v2/pokemon/{pokemon_number}/'
    response = requests.get(url)
    pokemon = response.json()
    return {
        'name': pokemon['name'],
        'id': pokemon['id'],
        'height': pokemon['height'],
        'weight': pokemon['weight'],
        'hp': pokemon['stats'][0]['base_stat'],
        'attack': pokemon['stats'][1]['base_stat'],
        'defense': pokemon['stats'][2]['base_stat'],
        'special-attack': pokemon['stats'][3]['base_stat'],
        'special-defense': pokemon['stats'][4]['base_stat'],
        'speed': pokemon['stats'][5]['base_stat'],
    }

# ---------------------- 读取历史分数 ----------------------
score_file = 'pokemon_scores.txt'
try:
    with open(score_file, 'r', encoding='utf-8') as f:
        print("=== 历史游戏记录 ===")
        for line in f:
            print(line.strip())
        print("===================")
except FileNotFoundError:
    print("暂无历史游戏记录")

# 初始化当前游戏分数
my_score = 0
opponent_score = 0

print("\n~~ Welcome to the Pokemon Top Trumps Game! ~~")
player1name = input("Player 1, please enter your name: ")
print(f"Hello {player1name}, get ready to enter the world of Pokemon!\n")

choice = True
while choice:
    my_pokemon = random_pokemon()
    print(f'You were given {my_pokemon["name"]}')
    stat_choice = input(
        'Which stat do you want to use? (id, height, weight, hp, attack, defense, special-attack, special-defense, speed) ')

    opponent_pokemon = random_pokemon()
    print(f'The opponent got {opponent_pokemon["name"]}')

    my_stat = my_pokemon[stat_choice]
    opponent_stat = opponent_pokemon[stat_choice]

    if my_stat > opponent_stat:
        print(f'Your value: {my_stat}')
        print(f'Opponent value: {opponent_stat}')
        print('You Win!')
        my_score += 1
        print(f"Your points: {my_score}")

    elif my_stat < opponent_stat:
        print(f'Your value: {my_stat}')
        print(f'Opponent value: {opponent_stat}')
        print('You Lose!')
        opponent_score += 1
        print(f"Opponent points: {opponent_score}")

    else:
        print(f'Your value: {my_stat}')
        print(f'Opponent value: {opponent_stat}')
        print('Draw!')

    play_again = input('Play again? (Y/N): ')
    if play_again.upper() != 'Y':
        choice = False

# ---------------------- 保存当前游戏分数 ----------------------
# 用追加模式('a')保存每次游戏记录，若想只保留最新记录可改为('w')覆盖模式
with open(score_file, 'a', encoding='utf-8') as f:
    record = f"玩家: {player1name} | 你的分数: {my_score} | 对手分数: {opponent_score}\n"
    f.write(record)
print(f"本次游戏记录已保存到 {score_file}")

三、关键代码解释 #

1. 函数位置调整：把random_pokemon()移到while循环外，避免每次循环重复定义函数，提升代码效率。
2. 读取历史记录：使用try-except处理文件不存在的情况，确保程序不会崩溃；若文件存在则逐行打印历史记录。
3. 保存记录：游戏结束时用with open(..., 'a')以追加模式写入文件，每次游戏记录会新增一行，方便查看所有历史成绩；如果只需要保留最新一次的成绩，将'a'改为'w'即可覆盖原有内容。
