使用pymongo對某一欄位進行sort時，報錯 TypeError: if no direction is specified, key_or_list must be an instance of list 問題程式碼：在mongo中執行沒有問題

count=db.three_province_poi_v9.find({ "sum_n.sum_4_x":{ $gt:0} } ).sort({"sum_n.sum_4_x":1}). count()

更正後：在python中執行

count=db_first.three_province_poi_v9.find({"sum_n.sum_4_x":{ "$gt":0} } ).sort([("sum_n.sum_4_x",1)]).count()
 

附：相關程式碼

from pymongo import MongoClient

def get_COUNT():
        Client=MongoClient('192.168.1.XXX',27017)
        db_first=Client.gaode_pois
        count=db_first.three_province_poi_v9.find   ({"sum_n.sum_4_x":{ "$gt":0} } ).sort([("sum_n.sum_4_x",1)]).count()
        print(count)
