# 记录单词
dics = {}


def add_dic():
    word = input('输入单词和中文翻译，空格分隔：')
    word = word.split(' ')
    dics[word[0]] = word[1]

def search_dic():
    word = input('输入单词查找中文翻译：')
    if word in dics:
        return dics[word]
    else:
        return '未找到单词【'+word+'】的中文翻译'

if __name__ == '__main__':
    while True:
        num = int(input('\n请选择操作：\n1.添加单词\n2.查找单词\n3.退出程序\n'))
        if num == 1:
            add_dic()
        elif num == 2:
            s = search_dic()
            print(s)
        elif num == 3:
            print('程序退出.')
            break
    

 

import sys

dic = {}

def add_dic(dic,word,ch):
    dic[word]=ch

def search_dic(dic,word):
    return dic[word]

if __name__ == "__main__":
    num = -1
    while num != 3:
        num = input("请输入操作数：");
        if num == '1':
            word = input("请输入单词：");
            ch = input("请输入中文：");
            add_dic(dic, word, ch)

        elif num == '2':
            word = input("请输入单词：");
            print(search_dic(dic, word))
        elif num == '3':
            sys.exit()
        else:
            print("输入错误")

结果如图
