Python背单词记单词小程序

好的，以下是一个简单的背单词记单词小程序的实现：

import random

# 单词类
class Word:
    def __init__(self, word, meaning):
        self.word = word
        self.meaning = meaning

# 词库类
class Vocabulary:
    def __init__(self):
        self.words = []

    # 添加单词
    def add_word(self, word, meaning):
        self.words.append(Word(word, meaning))

# 背单词程序类
class WordLearning:
    def __init__(self, vocabulary):
        self.vocabulary = vocabulary
        self.current_word = None
        self.score = 0
        self.wrong_words = []

    # 随机选择一个单词
    def get_word(self):
        self.current_word = random.choice(self.vocabulary.words)

    # 展示单词并获取用户输入
    def show_word(self):
        print("单词：", self.current_word.word)
        answer = input("请输入单词的意思：")
        return answer

    # 检查用户输入的答案是否正确
    def check_answer(self, answer):
        if answer == self.current_word.meaning:
            self.score += 1
            print("回答正确！")
        else:
            self.wrong_words.append(self.current_word)
            print("回答错误！正确答案为：", self.current_word.meaning)

    # 展示得分情况
    def show_score(self):
        print("本次得分：", self.score)

    # 展示错词并重新学习
    def review_wrong_words(self):
        if self.wrong_words:
            print("以下是你错过的单词：")
            for word in self.wrong_words:
                print(word.word, word.meaning)
            print("重新学习！")
            self.wrong_words = []
            self.score = 0
            self.start_learning()
        else:
            print("没有错过的单词！")

    # 开始学习
    def start_learning(self):
        print("开始学习！")
        while True:
            self.get_word()
            answer = self.show_word()
            self.check_answer(answer)
            another_word = input("是否继续？（y/n）")
            if another_word.lower() == "n":
                break
        self.show_score()
        self.review_wrong_words()

# 示例
vocabulary = Vocabulary()
vocabulary.add_word("apple", "苹果")
vocabulary.add_word("banana", "香蕉")
vocabulary.add_word("cherry", "樱桃")
vocabulary.add_word("orange", "橙子")
vocabulary.add_word("pear", "梨子")

word_learning = WordLearning(vocabulary)
word_learning.start_learning()

这个程序很简单，只有一个学习模式，用户输入单词的意思，程序判断是否正确，最后展示得分情况和错词，并可以重新学习错词。如果需要更多的学习模式和功能，可以根据需要进行扩展。
