print(data["changeorderdetail"][0]["ticketstatus"][0]["ticket_no"])
print(data[“changeorderdetail”][0].get(“ticketstatus”)[0].get(“ticket_no”)) print(data[“changeorderdetail”][0][“ticketstatus”][0][“ticket_no”])
这两句的结果是一样的。
总结如下： 1）要想获取字典的某个key的值，直接通过key的名称就可以，如data[“changeorderdetail”] 2）除了通过key的名称，也可以通过: 字典名称.get(“key名称”)方式获取。 3）如上代码，表示字典中存在着列表，字典等多级嵌套，这种情况下想获得最深一级的键值，同上逐级获取就可以了。
