Question

由于某种原因，行“new1 = [chr（x）for x in new]”不能采用浮点数。我将“新”列表中的所有ASCII整数转换回带有字符的列表，根据它们各自的ASCII号，该列表将保存为new1。

if de == "d":
   num = input("input ur number: ")
   key = int(input("Decryption key?"))
   num = [int(x) for x in num.split()]
   new = [x /key for x in num]
   new1 = [chr(x) for x in new]

这是错误：

- Traceback（最近一次调用最后一次）：文件“C：\ Python34 \ Encryptiontrue.py”，第23行，in new1 = [chr（x）for x in new]

- 文件“C：\ Python34 \ Encryptiontrue.py”，第23行，in new1 = [chr（x）for x in new]

- TypeError：期望的整数参数，浮点数

完整代码：

de = input("Decrypt or encrypt?: ")

if de == "e":
   word = input("input ur text: ")
   word = word.lower() 
   new = list(word)

   key = int(input("what number by?: "))

   new1 = [ord(x) * user for x in new]

   new2 = " ".join(str(x) for x in new1)
   print(new2)

if de == "d":
   num = input("input ur number: ")
   key = int(input("Decryption key?"))
   num = [int(x) for x in num.split()]
   new = [x /key for x in num]
   new1 = [chr(x) for x in new]

到

new = [x / key for x in num]

在Python 3中，new = [x // key for x in num]表示“真正的除法”，它总是返回一个浮点数。 /表示“地板划分”。如果两个参数都是整数，则Floor division将返回一个整数。有关详细信息，请参阅{{3}}。
