python列表中的字典排序， 先按第一个键排序，再按第二个键排序

Question

dl = [
{
    "viewTimes": 236,
    "topTimes": 49,
    "stepsNum": 76,
    "collTimes": 321
},
{
    "viewTimes": 236,
    "topTimes": 47,
    "stepsNum": 58,
    "collTimes": 344
},
{
    "viewTimes": 238,
    "topTimes": 53,
    "stepsNum": 11,
    "collTimes": 321
},
{
    "viewTimes": 240,
    "topTimes": 31,
    "stepsNum": 39,
    "collTimes": 344
},
{
    "viewTimes": 240,
    "topTimes": 38,
    "stepsNum": 13,
    "collTimes": 200
}]

我想对上面的列表里面的字典进行排序，先按viewTimes降序排列，再按stepsNum进行升序排列

Answer 1

items = sorted(dl,key=lambda x:(-x["viewTimes"],x["stepsNum"]))
print(items)

#两行代码即可，
