从 Python 中的不同文件创建 Object

Question

我正在尝试一个涉及多个文件的项目。 . 这个 object 是两个对象的组合。 这些文件位于 Py Charm 2020.3 上。 我已尝试添加一个init ，如本问题所示（ Create Python object from different.py 文件）我收到的错误消息是没有模块。 整个错误消息如下。

Traceback（最近一次调用最后）：文件“C：/Users/Aku/ImportExports/Message/TellAndReciveMessage.py”，第 2 行，来自 Tell 导入 TellMessage ModuleNotFoundError：没有名为“Tell”的模块

告诉消息文件：

class TellMessage:
    def __init__(self, msg:str) -> None:
        self.msg = msg

    def show(self) -> None:
        print(self.msg)


def main() -> None:
    tell_message = TellMessage("hello world")
    tell_message.show()

if __name__ == "__main__":
    main()

#Tell and Receive Message File 


from Message import TellMessage

class TellAndReciveMessage:
    def __init__(self, tell:TellMessage, recived:str):
        self.tell = tell
        self.recived = ""

    def get_recived(self) -> str:
        return self.recived

    def show(self) -> None:
        self.tell.show()
        self.recived = input(">>")

def main() -> None:
    tell = TellMessage("hello world")
    both = TellAndReciveMessage(tell, "")
    tell.show()
    print(tell.get_recived())

if __name__ == "__main__":
    main()

从消息导入 TellMessage

def get_recived(self) -> str:
    """
    Output: recived string (idenpotent)

    """

    if not self.tell:

        return
    self.tell.show()
    self.recived = input(">>")

def main() -> None: """ Input: None Output: None 注意：在命令行上运行代码和 output

"""

#Here is the line that fixes it (can call function)
tell = TellMessage.make("hello world")
both = TellAndReciveMessage(None, "")
both.show()
print(both.get_recived())

如果名称== “主”：主（）
