问题描述
我有以下 12 项配对 ["key",values] 的列表。 例如第一项是：["SN00003025",0.1]
["SN00003025",0.1],["SN00013002",30000.0],["SN00037509",23.7],["SN00126162",13560.0],["SN00155812",7.8],["SN00232427",3000.0],["SN00316328",12.0],["SN00319987",5456.0],["SN00339436",5600.0],["SN00399476",12500.0],["SN00399477",32.0],["SN00399478",1100.0]
如何将这个列表的项目顺序更改为随机？
解决方法
import random
random.shuffle(my_list)
您可能正在寻找类似 private boolean isNetworkConnected() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
return cm.getActiveNetworkInfo() != null && cm.getActiveNetworkInfo().isConnected();
}
