python写一个背单词软件

在Python中编写一个简单的背单词软件，可以利用字典数据结构存储单词列表，并结合随机选择、提示、复习等功能。这里提供一个基础框架的示例：

import random

class Flashcard:
    def __init__(self, word, definition):
        self.word = word
        self.definition = definition
        self.revealed = False

class VocabularyApp:
    def __init__(self):
        self.words = ['apple', 'banana', 'cherry', ...]  # 这里可以替换为实际的单词列表
        self.current_card_index = 0

    def shuffle_words(self):
        random.shuffle(self.words)

    def show_card(self):
        if not self.current_card_index < len(self.words):
            return "No more cards left!"
        
        card = self.words[self.current_card_index]
        if not card.revealed:
            return f"Word: {card.word}\nDefinition: (hide for review)"
        else:
            return f"You have already reviewed '{card.word}'.\nNext card?"

    def reveal_definition(self):
        card = self.words[self.current_card_index]
        card.revealed = True
        return f"The definition is: {card.definition}"

    def review(self):
        card = self.show_card()
        if "Next card?" in card:
            self.current_card_index += 1
        else:
            return self.reveal_definition()

# 使用示例
app = VocabularyApp()
app.shuffle_words()
while True:
    print(app.show_card())
    user_input = input("Enter 'r' to review or any other key to continue: ")
    if user_input.lower() == 'r':
        app.review()

这个示例只是一个基本的框架，你可以添加用户输入验证、计分系统、学习进度跟踪等更高级的功能。
