$(function() {$(".datepicker").datepicker({ maxDate: '0',dateFormat: 'dd-mm-yy' })});</script>

它在形式上的棘手错误:输入有效日期

我试图使用neo4j-driver将Django连接到Neo4j，但出现安全错误。

错误是：-neo4j.exceptions.SecurityError: Failed to establish secure connection to '[SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:600)'

是否有任何方法可以检查网络范围内的某些IP地址是否存在于另一个IP范围的子网中？

Example: 10.0.1.0/18 in 123.1.0.0/8 

如果它存在,我需要它返回True,否则返回False.
