我希望你能帮忙看一下代码
@Configuration
public class JpaConfiguration {
@Bean()
public LocalContainerEntityManagerFactoryBean entityManagerFactory(){
LocalContainerEntityManagerFactoryBean emFactory = new LocalContainerEntityManagerFactoryBean();
emFactory.setPersistenceProviderClass(FilterEnableHibernatePersistenceProvider.class);
//yours configuration
}
我想要它,以便如果指定的人已经在列表中,它将他们的新统计数据添加到3的列表并推出最旧的一个(在while循环中得到的那个),但我想添加该人到嵌套列表的末尾,如果它们还没有出现(新条目),请看一下#this是我的头脑中的部分!
为时已晚,我喝了过多杜松子酒吗?
请帮助我的大脑疼痛

制作这样的功能。它可以帮到你。
def is_elem(l, e):
return any(e==i[0] for i in l)
实施例
In [2]: sheros=[['Groot',23,34,35],['Rocket',45,56,67]]
In [3]: is_elem(sheros, 'Groot')
Out[3]: True
In [4]: is_elem(sheros, 'Other')
Out[4]: False
