疑似while循环的BUG，有人知道不？脑瓜子嗡嗡的

Question

python的bug吗？while循环里一带try except 他就说break在循环外，去掉try except就不报错了，正常运行了，这是为嘛呀

```python
i=0
while True:
    h='https://club.jd.com/comment/productPageComments.action?&productId=67308286187&score=3&sortType=6&page='
    t='&pageSize=10&isShadowSku=0&fold=1'
    url=h+str(i)+t
    #请求头
    headers={'User-Agent': 
         'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36'}
    response=requests.get(url=url,proxies=proxies,headers=headers)
try:
    json_data=response.json()
except:
    #print(f"err data: ", response.text)
    comments_list=json_data['comments']
    time.sleep(random.randint(12,20))
    i=i+1
    print('----------------------正在爬取第',i,'页-------------------------------------------')
    for commnet in comments_list:
        content=commnet['content']                #评论内容
        content=re.sub(r'[\t\n]','',content)              #把评论的换行给删除
        creationTime=commnet['creationTime']      #创建时间
        productColor=commnet['productColor']      #产品款式
        productSize=commnet['productSize']        #产品尺寸
        nickname=commnet['nickname']              #用户名称
        replyCount=commnet['replyCount']          #评论人数
        score=commnet['score']                    #评分
        usefulVoteCount=commnet['usefulVoteCount']#点赞数
        print(nickname,content,creationTime,score)
        csv_writer.writerow([nickname,content,creationTime,productColor,productSize,replyCount,score,usefulVoteCount])
        (random.randint(3,5))
    if i>12:
        break
f.close()

SyntaxError: 'break' outside loop

while, try except在同一级，try except进行缩进。然后try except中代码缩进。

i=0
while True:
    h='https://club.jd.com/comment/productPageComments.action?&productId=67308286187&score=3&sortType=6&page='
    t='&pageSize=10&isShadowSku=0&fold=1'
    url=h+str(i)+t
    #请求头
    headers={'User-Agent': 
         'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36'}
    response=requests.get(url=url,proxies=proxies,headers=headers)
    try:
        json_data=response.json()
    except:
        #print(f"err data: ", response.text)
        comments_list=json_data['comments']
        time.sleep(random.randint(12,20))
        i=i+1
        print('----------------------正在爬取第',i,'页-------------------------------------------')
        for commnet in comments_list:
            content=commnet['content']                #评论内容
            content=re.sub(r'[\t\n]','',content)              #把评论的换行给删除
            creationTime=commnet['creationTime']      #创建时间
            productColor=commnet['productColor']      #产品款式
            productSize=commnet['productSize']        #产品尺寸
            nickname=commnet['nickname']              #用户名称
            replyCount=commnet['replyCount']          #评论人数
            score=commnet['score']                    #评分
            usefulVoteCount=commnet['usefulVoteCount']#点赞数
            print(nickname,content,creationTime,score)
            csv_writer.writerow([nickname,content,creationTime,productColor,productSize,replyCount,score,usefulVoteCount])
            (random.randint(3,5))
    if i>12:
        break；
f.close()
