迭代通过json对象/字典

Question

abc = { 
"orders": [ 
    { 
     "orderID": 5, 
     "cost": 10, 
     "sell": 15 
    }, 
    { 
     "orderID": 6, 
     "cost": 8, 
     "sell": 12 
    }, 
    { 
     "orderID": 7, 
     "cost": 15, 
     "sell": 26   
     } 
    ] 
} 

for key, value in abc.items(): 
print (value["orderID"]) 

我想提取orderID值，但似乎无法使这项工作。它应回应 5,6,7

Answer 1

现在你正在循环的abc字典。相反，你要循环abc['orders']：

for order in abc['orders']: 
    print (order["orderID"]) 

Answer 2

for d in abc['orders']: 
    print (d["orderID"]) 

abc有一个关键orders这是一个list.So你可以遍历列表。
