求助，python27改到python36的问题

data = reg0.sub('',html)
data = reg1.sub('', data)
data = reg2.sub('',data)
data = reg3.sub('',data)
data = reg4.sub('',data)
data = json.loads(data)#data1的内容为一个字典，用{}括起来的内容

for i in data['comments']:
content = i['content'].encode('gbk')
content = content.replace("\n", "")
content1.append(i['content'].replace("\n", ""))
file.write(content +'\n')

for i in range(0,2):
url = 'https://sclub.jd.com/comment/productPageComments.action?callback=fetchJSON_comment98vv22312&productId=4538887&score=0&sortType=5&page='+ str(i) +'&pageSize=10&isShadowSku=0&rid=0&fold=1'
crawlProductComment(url,i)
time.sleep(1)
#print content1
#将前面提取的各字段信息汇总为table数据表，以便后面分析
table=pd.DataFrame({'productName':productName1,'commentTime':commentTime1,'content':content1})
#print table
#将creationTime字段更改为时间格式
table['commentTime']=pd.to_datetime(table['commentTime'])
#设置creationTime字段为索引列
#table = table.set_index('commentTime')
table.to_csv('f://spiderTest//jd_table_phone.csv',mode='w', encoding='utf-8',header = None)
#table.to_csv('f://spiderTest//jd_table_phone1.csv',mode='w', encoding='gbk',header = None)
file.close()

为什么使用python27程序可以运行，换了python36就一直报错，为什么老是字符串和byte的问题

[欢乐的小猪]

content = i['content'].encode('gbk') 改为 content = i['content']

3中就是修改了2中的编码。需要处理一下

你要把报错的提示发出来啊，提示说是哪一行哪一句，给我们看着才知道是什么原因 啊
