Python中怎么实现英语词典

以下是Python实现英语词典的一个简单例子：

# 定义一个空字典，用于存储单词和它们的定义
dictionary = {}

# 添加单词及其定义
dictionary['hello'] = 'used as a greeting or to begin a telephone conversation'
dictionary['world'] = 'the earth, together with all of its countries and peoples'

# 查找单词及其定义
word = input('Enter a word to search: ')
if word in dictionary:
    print(dictionary[word])
else:
    print('The word is not in the dictionary.')

# 删除单词及其定义
word = input('Enter a word to delete: ')
if word in dictionary:
    del dictionary[word]
    print('The word has been deleted.')
else:
    print('The word is not in the dictionary.')

# 翻译单词
from translate import Translator
translator= Translator(to_lang="zh")
translation = translator.translate("Hello World!")
print(translation)

# 实现单词联想功能
prefix = input('Enter a prefix to search: ')
for word in dictionary:
    if word.startswith(prefix):
        print(word)

这个例子中，我们使用了一个空字典来存储单词及其定义。我们可以通过添加、查找、删除、翻译单词以及实现单词联想功能来操作这个字典。
