How do locate same tag and click the target tag?

[utmcontent]

Suppose I have a bunch of tags in the page:

from os import stat,listdir,getcwd,rename,walk,listdir,remove,mkdir
from re import compile,search,match
from os.path import splitext,exists
from datetime import datetime
from json import dump,load,loads
import sys,io
from random import randint
from time import sleep
import time
import re
from helium import *
sys.stdout = io.TextIOWrapper(sys.stdout.buffer,encoding='utf-8')
import argparse
class DeleteSome(object): 
    def __init__(self):
        # write("Hello World!")
        start_chrome("www.baidu.com")
        #login
        click("登录")
        click("用户名登录")
        write("myusername", into="手机/邮箱/用户名")
        write("mypwd", into="密码")
        click("登录")
        sleep(10)
        #Suppose go to page like a "Chinese" reddit page
        go_to('https://tieba.baidu.com/p/7287171441?pn=1')
        url=Link("尾页").href
        print (url,dir(url))
        go_to(url)
        c=find_all(S("//li[@class='d_name']"))
        #filter wrong advertising tag
        c=[i for i in c if i.web_element.text.strip()!="逍遥加速器" and i.web_element.text.strip()!="51星变"]
        dddd=[i.web_element.text.strip() for i in c]
        print (dddd)
        #find
        d=find_all(S("//div[@class='core_reply_tail clearfix']"))
        eee=find_all(S("//span[@class='tail-info']"))
        eee=[j for i,j in enumerate(eee) if re.search("\d{1,}楼",j.web_element.text)]
        print(len(c),len(d),len(eee))#iterate tags must have same length and in same div tag
        #iterate
        for i,j,k in zip(c,d,eee):
            dname=i.web_element.get_attribute('data-field')
            string_flag=k.web_element.text
            if dname=='{"user_id":1258865446}':
                sleep(2)
                string_flag=k.web_element.text
                print ("find tag")
                print(string_flag)
                #find specfic tag and delete
                if Link("删除", to_left_of=string_flag).exists():
                    print("按钮存在")#can find but cannot click right tag
#This is the issue I cant click the right delete tag with to_left_of parameter,while I can use click("删除") delete the first tag how do I use to_left_of to_right_of tag ,Documentation is not very clear.
                    click(Link("删除",to_left_of=string_flag))

                    sleep(5)
                    click("确认")
                else:
                    print("按钮不存在")
        sleep(10)
        end=True
        if end:
            kill_browser()

if __name__=='__main__':
    f=[]
    parser = argparse.ArgumentParser(description='命令行中传入文件名')
    parser.add_argument("--fname",nargs="+",default=f,help="文件名")
    args = parser.parse_args()
    instance=DeleteSome()

How do I get tag inside tag attribute in iteration tag?
How do I click the certain same tag with other tag when locate the tag in forloop?
