如何从字典中获取随机值并仅打印键？

Question

我正在尝试编写以下猜词游戏，但出现类型错误。如何解决？谢谢！

import random

Dictionary = {"fruits":"watermelon", "buildings": "apartment", "mammal": "horse", "occupation": "fireman"}


def choose_word():
    hint, chosen_word = random.choice(Dictionary.items())
    print("Hint: " + hint)
    blank = []
    for letter in chosen_word:
        blank.append("_")
    print("".join(blank))
    return chosen_word

Answer 1

即使您在代码段的最后一行有错别字，我也不认为修复它会起作用。所以试试这个。

import random

Dictionary = {"fruits": "papaya", "buildings": "apartment", "mammal": "horse"}


def choose_word():
    hint, chosen_word = random.choice(list(Dictionary.items()))
    print("Hint: " + hint)

choose_word()

此处 Dictionary.items() 返回键值对的元组。对于 random.choice()，我们选择了一个这样的元组。然后我们将相应的键值分别解包到 hint 和 chosen_word。
