Question

我想根据分配从列表中删除json数据。如果分配：True 那么，那个特定的josn应该从字典中删除。在下面的数据中 {＆＃34; paperWidth＆＃34;：＆＃34; 4＆＃34;，＆＃34;分配＆＃34;：正确，＆＃34;型号＆＃34;：＆＃34; RB3150＆＃34;，＆＃34; connType＆＃34;：[＆＃34; Lan＆＃34;，＆＃34; Wifi＆＃34;，＆＃34; BlueTooth＆＃34;]，＆＃34; commandSet＆＃34 ;：＆＃34; TVSPOS＆＃34;}

所以这应该从我的最终对象中删除。如何在python中执行此操作。

d = {"allPrinters": [{"models": [{"paperWidth": "4","allocation": True,"model": "RB3150","connType": ["Lan","Wifi","BlueTooth"],"commandSet": "TVSPOS"},{"paperWidth": "4","allocation": False,"model": "RB3151","connType": ["Lan","Wifi"],"commandSet": "TVSPOS"}],"active": True,"make": "TVS","_id": "59e6f670f532eb1260b50cd9"},{"models": [{"paperWidth": "4","allocation": False,"model": "EP3160","connType": ["Lan","Wifi"],"commandSet": "ESCPOS"},{"paperWidth": "4","allocation": True,"model": "EP3161","connType": ["Lan"],"commandSet": "ESCPOS"}],"active": True,"make": "EPSON","_id": "59e6fc8ff532eb1260b50cf4"}]}

我不确定你要删除的东西是整个打印机还是只是模型，但这应该适用于前一种情况并且很容易转换为后者（转储continue并替换d['allPrinters']与model}：

for i, printer in enumerate(d['allPrinters']):
     for model in printer['models']:
         if model['allocation']:
             d['allPrinters'].pop(i)
             continue

从字典中删除元数据基于Python的布尔值
