sendLine不会发送整数（扭曲的Python）

Question

我正在使用Twisted库在Python中编写MUD。我目前正在尝试通过sendLine方法将整数发送到LineReceiver模块。然而，每当我试图发送一个整数，我得到了以下错误消息，运行我的程序时：

Unhandled Error 
Traceback (most recent call last):

sendLine 
    return self.transport.write(line + self.delimiter) 
exceptions.TypeError: unsupported operand type(s) for +: 'int' and 'str' 

这是造成错误的代码行是：

self.sendLine(SomeVarWhichIsANumber) 

Answer 1

所以...发送一个字符串：

self.sendLine(str(SomeVarWhichIsANumber))
