如何在python

Question

所以我试着编写一个加密word文档并在另一个文档中解密的程序。如果我把密钥放入程序但我想让它从key.txt读取密钥，我能够让程序工作。当我将密钥放入程序时，我不断收到错误（AttributeError：＆＃39; str＆＃39;对象没有属性＆＃39; items＆＃39;）。任何帮助表示赞赏。感谢

这是密钥文件包含的内容 {＆＃39; A＆＃39;：＆＃39; 6＆＃39;＆＃39; a＆＃39;＆＃39;〜＆＃39;，＆＃39; B＆＃39;：＆＃39 ; 66＆＃39;，＆＃39;＆＃39;＆＃39 ;;＆＃39;，＆＃39; C＆＃39;：＆＃39;＆lt;＆＃39;，＆＃39; c＆ ＃39;：＆＃39; @＆＃39;，＆＃39; D＆＃39;：＆＃39;％$＆＃39;，＆＃39; d＆＃39;：＆＃39;＃＆＃39 39;，\ ＆＃39; E＆＃39;＆＃39; 5＆＃39;，＆＃39; e＆＃39;＆＃39; $＆＃39;，＆＃39; F＆＃39;：＆＃39; 3＆＃39;，＆＃39; f＆＃39;：＆＃39;％＆＃39;，＆＃39; G＆＃39;：＆＃39; 71＆＃39;，＆＃39; g＆＃39; ：＆＃39; ^＆＃39;，＆＃39; H＆＃39;：＆＃39; 72＆＃39;，＆＃39; h＆＃39;：＆＃39;＆amp;＆＃39;，＆ ＃39;我＆＃39;＆＃39; 4＆＃39;，＆＃39;我＆＃39;：＆＃39; *＆＃39;，\ ＆＃39; J＆＃39;＆＃39; 74＆＃39;，＆＃39; j＆＃39;：＆＃39;（＆＃39;，＆＃39; K＆＃39;：＆＃39; 75＆＃39;，＆＃39;＆＃39;）＆＃39;，＆＃39; L＆＃39;：＆＃39; 1＆＃39;，＆＃39; l＆＃39; ：＆＃39; _＆＃39;，＆＃39; M＆＃39;：＆＃39; 77＆＃39;，＆＃39; m＆＃39;：＆＃39;`＆＃39;，＆＃39; ; N＆＃39;：＆＃39; /：＆＃39;，\ ＆＃39; n＆＃39;＆＃39; - ＆＃39;，＆＃39; O＆＃39;＆＃39; 79＆＃39;，＆＃39; o＆＃39;：＆＃39; +＆＃39;，＆＃39; P＆＃39;：＆＃39; 2＆＃39;，＆＃39; p＆＃39;：＆＃39; =＆＃39;，＆＃39; Q＆＃39 ;：＆＃39; 99＆＃39;，＆＃39; q＆＃39;：＆＃39; 9＆＃39;，＆＃39; R＆＃39;：＆＃39; 82＆＃39;，＆＃39; ;＆＃39;＆＃39;＆gt;＆＃39;，＆＃39; S＆＃39;：＆＃39; 83＆＃39;，\ ＆＃39;＆＃39; [＆＃39;，＆＃39; T＆＃39;：＆＃39;＆＃39;＆＃39; t＆＃39;：＆＃39; ]＆＃39;，＆＃39; U＆＃39;：＆＃39;;＆＃39;，＆＃39; u＆＃39;：＆＃39; {＆＃39;，＆＃39; V＆＃ 39;：＆＃39; 86＆＃39;，＆＃39; v＆＃39;：＆＃39;}＆＃39;，＆＃39; W＆＃39;：＆＃39; 7＆＃39;，＆ ＃39; w＆＃39;：＆＃39; /＆＃39;，\ ＆＃39; X＆＃39;：＆＃39; / +＆＃39;，＆＃39; x＆＃39;：＆＃39; 8＆＃39;，＆＃39; Y＆＃39;：＆＃39; ;％（＆＃39;，＆＃39; y＆＃39;：＆＃39; 0＆＃39;，＆＃39; Z＆＃39;：＆＃39; 90＆＃39;，＆＃39; z＆＃ 39;：＆＃39; $ 122＃39;}

继承人加密

def main():

codes = open('key.txt', 'r')
code = codes.read()

inputfile = open('text.txt', 'r')
paragraph = inputfile.read()
inputfile.close()

encrypt = open('Encrypted_File.txt', 'w')
for ch in paragraph:
    if ch in code:
        encrypt.write(code[ch])
    else:
        encrypt.write(ch)
encrypt.close()

main()

继承人解密

def main():
codes = open('key.txt', 'r')
code = codes.read()

inputfile = open('Encrypted_File.txt', 'r')
encrypt = inputfile.read()
inputfile.close()

code_items = code.items()


for ch in encrypt:
    if not ch in code.values():
        print(ch, end='')
    else:
        for k,v in code_items:
            if ch == v:
                print(k, end='')
main()

Answer 1

code = codes.read()

此时code是一个字符串，在读取文件时总是如此。 Python不会自动找出将其转换为什么，特别是因为文件可以包含任何字面意思。要转换为字典：

from ast import literal_eval

code = literal_eval(codes.read())
