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。但是，每当我尝试发送一个整数时，我在运行程序时会收到以下错误消息：

Unhandled Error

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

导致错误的行是：

self.sendLine(SomeVarWhichIsANumber)

Answer 1

所以......发一个字符串：

self.sendLine(str(SomeVarWhichIsANumber))

sendLine不会发送整数（Twisted Python）
