小白初学 Python ，有没有大佬可以帮忙简化一下代码

import pandas as pd
import openpyxl
#用来保存结果的列表
two = []
urltwo = []
urltwoo = []

three = []
urlthree = []
urlthreee = []

four = []
urlfour = []
urlfourr = []

five = []
urlfive = []
urlfivee = []

letters = "abcdefghijklmnopqrstuvwxyz"

#几位数，自己定
ttwo = [a+b for a in letters for b in letters]
tthree = [a+b+c for a in letters for b in letters for c in letters]
ffour = [a+b+c+d for a in letters for b in letters for c in letters for d in letters]
ffive = [a+b+c+d+e for a in letters for b in letters for c in letters for d in letters for e in letters]
#域名后缀
hz = "logistics.com.br"
hz2 = "comex.com"

#开始
for k2 in ttwo:
url2 = [k2 + hz]
url22 = [k2 + hz2]

urltwo.append(url2)
urltwoo.append(url22)
two = urltwo + urltwoo

for k3 in tthree:
url3 = [k3 + hz]
url33 = [k3 + hz2]

urlthree.append(url3)
urlthreee.append(url33)
three = urlthree + urlthreee

for k4 in ffour:
url4 = [k4 + hz]
url44 = [k4 + hz2]

urlfour.append(url4)
urlfourr.append(url44)
four = urlfour + urlfourr

for k5 in ffive:
url5 = [k5 + hz]
url55 = [k5 + hz2]

urlfive.append(url5)
urlfivee.append(url55)
five = urlfive + urlfivee

#导出结果
data = {'两个字母': two,'三个字母': three,'四个字母': four,'五个字母':five}
frame = pd.DataFrame(data)
frame.to_excel("E:\BaiduNetdiskWorkspace\个人\python\猜域名.xlsx")

#感谢大家的建议，修改了一下代码，但是还是有两个问题，烦请各位大佬指点迷津
#问题 1：不知道怎么处理 letter_permutations 才能组成 ab,ac,ad 这样的组合
#问题 2：怎么才能去掉生成的 excel 第一列默认的数字索引
import string
import itertools
import pandas as pd
import openpyxl
import requests
import sys

#Lowercase_alphabet,小写字母表
Lowercase_alphabet = string.ascii_lowercase

url = []
result_url = []

#定义一个函数来生成 url
def web_guessing(n,domain)
n = input('请输入你想生成几位数的组合')
domain = raw_input('请输入你想组合的域名')
letter_permutations = list(itertools.permutations(Lowercase_alphabet,n))

#不知道怎么处理 letter_permutations 才能组成 ab,ac,ad 这样的字符串组合

#将字母组合和域名组成网址
for permutations in letter_permutations:
url = [permutations+domain]
#检测状态码，储存有效的 url
r=requests.get(url,timeout=5)
code = r.status_code
if code == 200:
result_url.append(url)

#进行数据转换，输出到 excel
data = {'%ｄ位字母的域名组合'%n : result_url}
frame = pd.DataFrame(data)
frame.to_excel("E:\BaiduNetdiskWorkspace\个人\python\域名\猜域名.xlsx")
return("结果保存在：E:\BaiduNetdiskWorkspace\个人\python\域名\猜域名.xlsx")

你这已经不是简化的问题了，看了一半，提出两点提醒：
1. 让变量名具有一定含义
2. letters 这个变量可以通过标准库 import string; string.ascii_lowercase 进行调用

你可以试试 itertools.product
ttwo = [''.join(chars) for chars in product(letters, repeat=2)]
或者用 ttwo * letters 去生成 tthree
tthree = [char + word for char in letters for word in ttwo]
或者用 letters * two 去生成 three
three = [[char + url[0]] for char in letters for url in two],这里顺序会不一致，如果要顺序一致，可以用 letters * two[0:len//2] + letters * two[len//2:]
