如何从字典列表中删除列表

def remove_list_from_dict_list(dict_list, to_remove):
    for d in dict_list:
        if isinstance(d, dict):
            keys_to_remove = []
            for key, value in d.items():
                if value == to_remove:
                    keys_to_remove.append(key)
                elif isinstance(value, list) and to_remove in value:
                    value.remove(to_remove)
            for key in keys_to_remove:
                del d[key]

# 示例用法
dict_list = [
    {"name": "John", "languages": ["Python", "Java", "C++"]},
    {"name": "Alice", "languages": ["Python", "JavaScript"]},
    {"name": "Bob", "languages": ["Java", "C#"]},
]

to_remove = ["Python", "Java"]
remove_list_from_dict_list(dict_list, to_remove)

print(dict_list)

[
    {"name": "Alice", "languages": ["JavaScript"]},
    {"name": "Bob", "languages": ["C#"]},
]
