獲取/設置串行類屬性

Question

我正在使用PySerial連接到Threaded連接。這是我簡單的第一個類繼承線程和運行串行：

from threading import Thread 
import serial, inspect 

class Serial1(Thread): 

def __init__(self,main_queue,port = "COM1") 

    self.ser = serial.Serial() 
    self.queue = main_queue 
    self.port = port 

def open(self): 

    self.ser.port = self.port 
    if self.ser.isOpen(): 
     self.ser.close() 
    self.ser.open() 
    Thread.__init__(self) 
    self.start() 

在那之後我又同級Serial2繼承主題，並使用接口Serial1：

from Queue import Queue 
from threading import Thread 
import serial1 

class Serial2(Thread): 

def __init__(self,main_queue,port = "COM2") 

    self.ser = serial1.Serial1() 
    self.queue = main_queue 
    self.port = port 

def open(self): 
    self.ser = serial1.Serial1(self.queue, self.port) 
    if self.ser.open() == True: 
     Thread.__init__(self) 
     if self.isAlive() == False: 
      self.start() 

做完這一切，我怎麼設置/在串口1和串口2上獲得串口的端口屬性？假設我使用接口Serial1和Serial2在腳本：

from Queue import Queue 
import serial2 
import serial1 

q1 = Queue(maxsize = 1) 
q2 = Queue(maxsize = 1) 

s1 = serial1.Serial1(q1, "COM4") 
s2 = serial2.Serial2(q2, "COM2") 

#get port value from Serial1 and Serial2 
port1 = s1.port 
port2 = s2.port 

#set Serial1 and Serial2 port value 
s1.port = "COM3" 
s2.port = "COM1" 

我以前在接口Serial1使用getter/setter方法試過了，但他們導致無限遞歸：

def getport(self): 
    return self.port 

def setport(self, port): #when first initialising self.port, it goes and get stuck here 
    self.port = port 

port = property(getport,setport) 

Answer 1

那麼，這是尷尬。

我終於得到了一個答案，這是相當短的：

def getport(self): 
    return self.ser.port 

def setport(self, port): 
    self.ser.port = port 

port = property(getport,setport)
