我正在做的一个项目是将文本转换为数字。（例如，“hello world”将转换为“8 5 12 12 15 27 23 15 18 12 4”）。

在我的代码的第 10 行中，for 循环导致以下错误消息：

Traceback (most recent call last):
  File "C:\Users\gabri\PycharmProjects\padding\main.py", line 15, in <module>
    converter(plaintext)
  File "C:\Users\gabri\PycharmProjects\padding\main.py", line 10, in converter
    for n in plaintext:
TypeError: 'types.GenericAlias' object is not iterable

Process finished with exit code 1

我的代码如下：

alphabet = ("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')


def getplaintext():
    global plaintext
    plaintext = list[input("Enter plaintext:.....")]
    print(plaintext)

def converter(plaintext):
    for n in plaintext:
        print(n)


getplaintext()
converter(plaintext)

有谁知道是什么导致了这个错误？
