python中的for语句不起作用

Question

试图制作一个简单的程序，将单词“supercaliflagilisticexpialidocious”显示为辅音替换为破折号。代码如下：

message = print("supercalifragilisticexpialidocious")

result_str = ""

CONSONANTS = "BCDFGHJKLMNPQRSTVXZWY"

print()

for letter in message:
    if letter not in CONSONANTS:
         result_str += letter

    else:
         result_str += "-"

print(result_str)

input("\n\nPress the enter key to exit:")

当我在模块中运行它时，它会正确地打印"message"，但会给出此错误，而不是打印"result_str"：

Traceback (most recent call last): File "F:/CSC119/final exam program 4.py", line 13, in <module> for letter in message: TypeError: 'NoneType' object is not iterable

那我有什么问题？？ 谢谢你

Answer 1

不能将print语句赋给变量。你需要做message = text而不是message = print(text)

Answer 2

message = "supercalifragilisticexpialidocious"

不打印
