方法一：使用字典实现

word_dict = { 'a': '一个', 'apple': '苹果', 'banana': '香蕉', 'cat': '猫', 'dog': '狗' }

word = input('请输入要翻译的单词：') if word in word_dict: print(word_dict[word]) else: print('No such word')

方法二：使用文件实现

with open('words.txt', 'r', encoding='utf-8') as f: word_list = f.readlines()

word_dict = {} for word in word_list: word = word.strip().split('：') word_dict[word[0]] = word[1]

word = input('请输入要翻译的单词：') if word in word_dict: print(word_dict[word]) else: print('No such word')
