python 生成字符串_Python字符串生成器，按照特定的顺序

我正在制作一个程序，运行时会根据我定义的字符列表生成一个随机字符串。的代码是：Python字符串生成器，按照特定的顺序

from random import randint

from random import *

import random

Upperletters=["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"]

Lowerletters = ["a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"]

Symbols = ["!","$","%","^","&","*","(",")","_","-","+","="]

Numbers = ["1","2","3","4","5","6","7","8","9","0"]

random.shuffle(Symbols)

random.shuffle(Numbers)

random.shuffle(Upperletters)

random.shuffle(Lowerletters)

randomlength = randint(8, 12)

stringgenerator = ''.join(choice(Upperletters + Symbols + Numbers +

Lowerletters) for x in range(randomlength))

print(stringgenerator)

stringgeneratorlower = stringgenerator.lower()

letter_combos = ["qwe","wer","ert","rty","tyu","yui","uio","iop","asd","sdf","dfg","fgh","ghj","hjk","jkl","zxc","xcv","cvb","vbn","bnm"]

keyboard =int(sum(stringgeneratorlower.count(fragment) for fragment in letter_combos))

if keyboard >= 1:

print("Bad try again")

但我的问题是，我想在他们添加的顺序使用符号串，所以它应该是大写字符，然后再一些符号然后一些数字和然后是小写字母。我的问题是，它会以完全随机的顺序生成它们。我怎样才能让它按照我想要的顺序生成它们，以便生成的字符串不包含列表中的任何letter_combos？要做到这一点

你想它使用Upperletters，Lowerletters，符号和数字的顺序，他们是在阵列中或做你想让它先用Upperletters，然后用Lowerletters，然后用符号和最后使用数字？ –

您的导入是冗余/不一致的。为什么不下定决心？ –

您能举出电流输出和期望输出的例子吗？ –
