【问题描述】：

所以我有一本字典，里面有一堆单词作为键，它们的定义作为值。

例如，word_list.txt

words = {
happy: "feeling or showing pleasure or contentment.", 
apple: "the round fruit which typically has thin green or red skin and crisp flesh.", 
today: "on or in the course of this present day."
faeces: "waste matter remaining after food has been digested, discharged from the bowels; excrement."
}

如何打印 Python 文本文件中字典中的随机单词？

【问题讨论】：

print(random.choice(words.keys()))
因为它目前代表 words 不是有效的字典
是的，word_list.txt 需要带引号的键和在 today 的值之后的逗号才能成为有效的 Python。
欢迎来到堆栈溢出！您似乎在要求某人为您编写一些代码。 Stack Overflow 是一个问答网站，而不是代码编写服务。请查看How to Ask 了解如何编写有效的问题。

一种方法

import random
    words = {
    "happy": "feeling or showing pleasure or contentment.", 
    "apple": "the round fruit which typically has thin green or red skin and crisp flesh.", 
    "today": "on or in the course of this present day.",
    "faeces": "waste matter remaining after food has been digested, discharged from the bowels; excrement."
    }
    
    id = random.sample(words.keys(),1)
    print(words[id[0]])
