Question

我的任务是创建一个解码凯撒密码的程序。我为此完成了大部分工作，它可以很好地完成每个可能的键并找到新单词。

当我尝试检查创建的单词时，会出现问题。

#---------------------------------
#this is a program that should brute force a ceaser cypher
#---------------------------------
#list of possible letters
x=['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']
y=input("Please input the string you want to decode:   ").lower()
new_string=''
#creates a list to check weather the unjumbled word is valid
AllowedWords = []
WordsFile = open("aqawords.txt", "r")
for Word in WordsFile:
  AllowedWords.append(Word.strip().lower())
WordsFile.close()
#does this 26 times to test all possible keys
for f in range (1,27):
    #does each letter individually
    for i in range(len(y)):
        #finds the numerical value for each leter
        y1=(x.index((y[i:(i+1)])))+1
        #adds the key to the letter's number
        y2=y1+f
        #makes sure it does not go out of range
        y2=y2%26
        #adds new letter to string
        new_string=new_string+str(x[y2-1])
        #this should check every different combination of letters
        for q in range(1,(len(new_string))+1):
            for q1 in range(1,(len(new_string))+1):
                #here is the problem-----------
                #checks what type the variables are
                print(type(q))
                print(type(q1))
                #attempts to create a new string to store these new words
                new_string_1=new_string[q,q1]
                #says "TypeError: string indices must be integers"
                #but i checked and above it says that they are ints
                if new_string_1 in AllowedWords:
                    print(new_string_1)
                #------------------------------
                #print(new_string_1)
        new_string_1=''
    #print(new_string)
    new_string=''

这就是我得到的结果：

RESTART: D:\!!computer science!!\!homework!\miss jackson's homework\cyphers\Ceasar cypher.py 
Please input the string you want to decode:   abc
<class 'int'>
<class 'int'>
Traceback (most recent call last):
  File "D:\!!computer science!!\!homework!\miss jackson's homework\cyphers\Ceasar cypher.py", line 35, in <module>
    new_string_1=new_string[q,q1]
TypeError: string indices must be integers
>>>

有人能找到我错的地方吗？
