我正在制作一個(gè)程序，運(yùn)行時(shí)會(huì)根據(jù)我定義的字符列表生成一個(gè)隨機(jī)字符串。 的代碼是：Python字符串生成器，按照特定的順序

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")

但我的問題是，我想在他們添加的順序使用符號(hào)串，所以它應(yīng)該是大寫字符，然后再一些符號(hào)然后一些數(shù)字和然后是小寫字母。我的問題是，它會(huì)以完全隨機(jī)的順序生成它們。我怎樣才能讓它按照我想要的順序生成它們，以便生成的字符串不包含列表中的任何letter_combos？要做到這一點(diǎn)

你想它使用Upperletters，Lowerletters，符號(hào)和數(shù)字的順序，他們是在陣列中或做你想讓它先用Upperletters，然后用Lowerletters，然后用符號(hào)和最后使用數(shù)字？ –

您的導(dǎo)入是冗余/不一致的。為什么不下定決心？ –

您能舉出電流輸出和期望輸出的例子嗎？ –
