我应该如何为此编写解密程序？

Question

我正在尝试使用Python 编写解密代码。加密工作并在名为 myfile 的文件中输出以下 119105108108 116104105115 11911111410763 ，其中包含“这有效吗？”。但我不知道如何解密它，也不知道它是否可以解密，希望得到一些帮助。

#declare variables
fo = 0
ascii_val = []
asci_val = []
asc_val = []
listtostr = 0
listtost = 0
listtos = 0
split_val = 0
x = 0

#open files
fo = open("myfile.txt","r")
fo1 = open("hora.txt","w")

#read text from files and put into a list    
txt = fo.read()
split_val = txt.split(" ")
print(split_val)

#process of encrypting using ascii values
for x in split_val[0]:
    y = x.split()
    a = ord(x)
    a =str(a)
    ascii_val.append(a)
    
print()

#process
for x in split_val[1]:
    a = ord(x)
    a =str(a)
    asci_val.append(a)
    
print()

#process
for x in split_val[2]:
    a = ord(x)
    a =str(a)
    asc_val.append(a)
    
#joining ascii values together
listtostr = "".join([str(x) for x in ascii_val])

listtost = "".join([str(x) for x in asci_val])

listtos = "".join([str(x) for x in asc_val])

#joining all of the ascii values together
b = listtostr + " " + listtost +" " + listtos
print(b)

#writing to new file
fo1.write(b)

#close files
fo.close()
fo1.close()
