我需要能夠接受輸入,刪除特殊字符,使所有大寫字母小寫,轉換爲偏移量爲5的ascii代碼,然後將這些現在的偏移值轉換回字符以形成一個字。我不斷收到類型錯誤:「詮釋」對象不是在最後如何將ascii碼轉換爲文本?
string=(str(raw_input("The code is:")))
#change it to lower case
string_lowercase=string.lower()
print "lower case string is:", string_lowercase
#strip special characters
specialcharacters="1234567890~`[email protected]#$%^&*()_-+={[}]|\:;'<,>.?/"
for char in specialcharacters:
string_lowercase=string_lowercase.replace(char,"")
print "With the specials stripped out the string is:", string_lowercase
#input offset
offset=(int(raw_input("enter offset:")))
#converstion of text to ASCII code
for i in string_lowercase:
code=ord(i)
result=code-offset
#converstion from ASCII code to text
for number in result:
message=repre(unichr(number))
print message
'result'是一個'int'。然後你試着迭代它。我認爲你想要的是'result.append(code - offset)'。這意味着你需要將'result'參數初始化爲'list',所以'result = []'應該放在你的循環之前。 – idjaw
