使用python批量造測試數據

# -*- coding:utf-8 -*-
import json
import os
import time

class Virtual_Data:

    def __init__(self):
        self.data1 = 0
        self.data2 = 0
        self.data3 = 0
        self.json = {}

    def json_file(self,num):
        fp = open("data.txt","a")
        while self.data1 <= num and self.data2 <= num and self.data3 <= num:
            now_time = time.localtime(time.time())
            timestamp = time.strftime("%Y-%m-%d %H:%M:%S",now_time)
            self.json = {"data1":("num"+"_"+str(self.data1)),"data2":self.data2,"data3":self.data3,"timestamp":timestamp}
            self.data1 += 1
            self.data2 += 1
            self.data3 += 1
            fp.writelines(json.dumps(self.json)+os.linesep)
            time.sleep(1)
        fp.close()

if __name__ == "__main__":
    Data = Virtual_Data()
    Data.json_file(10)

執行結果：

{"timestamp": "2019-12-23 15:46:48", "data1": "num_0", "data3": 0, "data2": 0}

{"timestamp": "2019-12-23 15:46:49", "data1": "num_1", "data3": 1, "data2": 1}
