问题描述

我有这样一个json数组

a = [
        {"id":863,"hostname":"hdfs"},
        {"id":822,"hostname":"admin"},
        {"id":865,"hostname":"Spark-1"},
        {"id":1074,"hostname":"Spark-10"},
        {"id":867,"hostname":"Spark-2"},
        {"id":1014,"hostname":"Spark-11"}
    ]

通过sort按 hostname字段排序

a.sort(key = lambda x:x["hostname"])

得到的是这样的结果Spark-10 在Spark-2前面

[
    {"id":822,"hostname":"admin"},
    {"id":863,"hostname":"hdfs"},
    {"id":865,"hostname":"Spark-1"},
    {"id":1074,"hostname":"Spark-10"},
    {"id":1014,"hostname":"Spark-11"},
    {"id":867,"hostname":"Spark-2"},

]

而我希望得到这样一个结果

[
    {"id":822,"hostname":"admin"},
    {"id":863,"hostname":"hdfs"},
    {"id":865,"hostname":"Spark-1"},
    {"id":867,"hostname":"Spark-2"},
    {"id":1074,"hostname":"Spark-10"},
    {"id":1014,"hostname":"Spark-11"}
]

请问我改如何进行处理
