As said in the comments, random.choice works with lists and not with dicts.正如评论中所说， random.choice适用于列表而不是字典。 You have two options:你有两个选择：
- Use the list of the keys of the dict:使用字典的键列表：
genre=choice(list(Myanimes.keys()))
print(genre, Myanimes[genre])
# Result: Fantasy ['Jujustsu Kaisen', 'Hunter x Hunter', 'Devilman Crybaby']
- Use the list of items, which are
(key, value)pairs使用项目列表，它们是(key, value)对
print(choice(list(Myanimes.items())))
# Result: ('Supernatural', ['Blue exorcist', "Jojo's Bizarre Adventure"])
