您必须遍历字典列表并使用给定的字典进行搜索id_number。一旦找到它，您就可以打印其其余数据并中断（假设id_number是唯一的）。
data = [
{
"id_number": "SA4784",
"name": "Mark",
"birthdate": None
},
{
"id_number": "V410Z8",
"name": "Vincent",
"birthdate": "15/02/1989"
},
{
"id_number": "CZ1094",
"name": "Paul",
"birthdate": "27/09/1994"
}
]
for i in data:
if i['id_number'] == 'V410Z8':
print(i['birthdate'])
print(i['name'])
break
如果您可以控制数据结构，则更有效的方法是使用id_number键作为键（同样，假设id_number是唯一的）：
data = { "SA4784" : {"name": "Mark", "birthdate": None},
"V410Z8" : { "name": "Vincent", "birthdate": "15/02/1989"},
"CZ1094" : {"name": "Paul", "birthdate": "27/09/1994"}
}
然后，您需要做的就是尝试直接访问它：
try:
print(data["V410Z8"]["name"])
except KeyError:
print("ID doesn't exist")
>> "Vincent"
