记录大佬sorted操作 

dl = [
{
    "viewTimes": 236,
    "topTimes": 49,
    "stepsNum": 76,
    "collTimes": 321
},

    "viewTimes": 236,
    "topTimes": 47,
    "stepsNum": 58,
    "collTimes": 344
},

},
{
    "viewTimes": 240,
    "topTimes": 38,
    "stepsNum": 13,
    "collTimes": 200
}]
# 按viewTimes升序排列，再按stepsNum升序排列
# dl2 = sorted(dl, key=lambda obj: (obj['viewTimes'], obj['stepsNum']), reverse=False)

# 按viewTimes升序排列，再按stepsNum降序排列
dl2 = sorted(dl, key=lambda obj: (obj['viewTimes'], -obj['stepsNum']), reverse=False)
dl_tmp['stepsNum'], reverse=False)
print(dl2)
for temp in dl2:
    print(temp)
