有没有更好的方法来检查字典中是否存在多个键，并根据找到的键将多个值赋给一个变量

def check_keys(dictionary, keys):
    if len(set(keys).intersection(dictionary.keys())) == len(keys):
        return True
    else:
        return False

# 示例用法
my_dict = {'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
my_keys = ['key1', 'key2', 'key3']

if check_keys(my_dict, my_keys):
    my_variable = [my_dict[key] for key in my_keys]
    print(my_variable)
else:
    print("Not all keys are present in the dictionary.")
