在Python中从字典中删除键值对列表中的特定值

def remove_specific_value(dictionary, value):
    keys_to_remove = []
    for key, val in dictionary.items():
        if val == value:
            keys_to_remove.append(key)
    for key in keys_to_remove:
        dictionary.pop(key)
    return dictionary

my_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 2}
value_to_remove = 2
result_dict = remove_specific_value(my_dict, value_to_remove)
print(result_dict)

{'a': 1, 'c': 3}
