html解码（'；utf-8'；）csv双线（python 3）

我通过API读取CSV转储，下载是一个字符串（见下面的示例），但当我将其解码为CSV文件时，数据行之间会有一个额外的空行

我需要做什么来删除这些额外的行

from urllib.request import urlopen
import json, ast
import datetime
import time
import LOM_Config
import LOM_GetTokenID

def CVS_Download(LOMID, LOMDeviceName):

    global dtime
    dtime = time.time()

token_string = LOM_GetTokenID.GetTokenID()
    tempstring = 'http://XXXXXXXXXXXXXXXX/' + str(LOMID) + '/csv/?token=' +  str(token_string) + '&timestamp_to=' + str(dtime)  + '&length_of_time=31557600' 
    file = urlopen(tempstring)
    html = file.read()
    print(html)
    html = html.decode('utf-8')
    tmpstring = LOMDeviceName + '.csv'
    f = open(tmpstring,'a')
    f.write(str(html))
    f.close

这是HTML转储

b'time,Light Level,Air Pressure,Humidity,Temperature,CO2,Pollution,Sound\r\n2017-04-01 06:55:00+00:00,56.0,1004.52001953125,56.7000007629395,20.7999992370605,0.0,0.0,38.2862205505371\r\n2017-04-01 06:56:00+00:00,142.0,1004.53002929688,56.5999984741211,20.7999992370605,0.0,0.0,37.7092018127441\r\n

CSV文件将变为

time,Light Level,Air Pressure,Humidity,Temperature,CO2,Pollution,Sound

bytestring可以独立于操作系统行为来处理文本。尝试在此文件模式下写入文件，例如：

teststring = b'time,Light Level,Air Pressure,Humidity,Temperature,CO2,Pollution,Sound\r\n2017-04-01 06:55:00+00:00,56.0,1004.52001953125,56.7000007629395,20.7999992370605,0.0,0.0,38.2862205505371\r\n2017-04-01 06:56:00+00:00,142.0,1004.53002929688,56.5999984741211,20.7999992370605,0.0,0.0,37.7092018127441\r\n'

f = open("testfile.csv", 'ab')  # <- 'b' = bytestring
f.write(teststring)  # <- without converting it to str
f.close()

teststring=b'时间、亮度、气压、湿度、温度、二氧化碳、污染、声音\r\n2017-04-01 06:55:00+00:00,56.01004.52001953125,56.700007629395,20.799992370605,0.0,0.0,38.286220505371\r\n2017-04-01 06:56:00+00:00142.01004.53002929688,56.5999984741211,20.799992370605,0.0,0.0.27431\r\r\n
f=open（“testfile.csv”，“ab”）#@BrendonShaw如果有效，欢迎接受我的答案。这将帮助其他人看到这是解决您问题的方法。
