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？ –
