如何用Python3实现Dictionary？-yiteyi-C++库

这个程序使用python的容器，名为词典（在字典中，一个键与一些信息相关联）。这个程序将把一个单词作为输入，并返回该单词的意思。 Python3应该安装在您的系统中。如果未安装，请从此安装链接。始终尝试安装最新版本。

我制作了一个文本文件，其中单词及其含义以python的字典格式存储 例子：

data = {"geek" : "engage in or discuss computer-related tasks 
obsessively or with great attention to technical detail."}

在这里，如果我们从数据中称之为“极客”，那么这将返回其含义“痴迷地从事或讨论与计算机相关的任务，或者非常关注技术细节”。

这个python程序允许您获取这个文本文件的数据并给出其含义。
