在python中获取与字典中的特定值对应的键

def get_keys_by_value(dictionary, value):
    keys = []
    for key, val in dictionary.items():
        if val == value:
            keys.append(key)
    return keys

def get_keys_by_value(dictionary, value):
    inverted_dict = {v: k for k, v in dictionary.items()}
    return inverted_dict[value]

def get_keys_by_value(dictionary, value):
    keys = [key for key, val in dictionary.items() if val == value]
    return keys
