python - 如何保存过去的高分？

Question

我目前有一个高分列表的代码:

scores = []
choice = None
while choice != "0":
    print(
    """
    High Scores
    0 - Quit
    1 - List Scores
    2 - Add a Score
    """
    )
    choice = input("Choice: ")
    print()
    if choice == "0":
        print("Goodbye")
    elif choice == "1":
        print("High Scores\n")
        print("NAME\tSCORE")
        for entry in scores:
            score, name = entry
            print(name, "\t", score)
    elif choice == "2":
        name = input("What is your name? ")
        score = int(input("What score did you get? "))
        entry = [score, name]
        scores.append(entry)
        scores.sort(reverse=True)
        scores = scores[:10]
    else:
        print("Sorry, but", choice, "isn't a valid choice.")

谁能告诉我如何添加代码，以便下次使用该程序时保存高分

Answer 1

您最好的选择是 json module :

import json

def load_scores():
    with open("scores.json") as infile:
        return json.load(infile)

def save_scores(scores):
    with open("scores.json", "w") as outfile:
        json.dump(scores, outfile)

现在您可以调用 save_scores(scores) 来保存当前的高分列表，并执行 scores = load_scores() 从文件中取回它们。
