我是python的新手,所以需要你的帮助以下错误信息。我有两个文件,第一个是“test1.py”,我正在运行并具有以下代码。
import sys, time, re, os, pickle
from ComLib import *
obj = Com()
obj.ComOpen()
obj.ComReset()
obj.ComClose()
,第二个文件是“ComLib.py”并具有以下代码
import serial, sys, re, pickle, time
class Com:
def ComOpen(self):
self = serial.Serial()
self.port = "COM1"
self.baudrate = 9600
self.bytesize = serial.EIGHTBITS #number of bits per bytes
self.parity = serial.PARITY_NONE #set parity check: no parity
self.stopbits = serial.STOPBITS_ONE #number of stop bits
self.timeout = 1 #non-block read
self.xonxoff = True #disable software flow control
self.rtscts = False #disable hardware (RTS/CTS) flow control
self.dsrdtr = False #disable hardware (DSR/DTR) flow control
self.writeTimeout = 2 #timeout for write
self.open()
return
def ComClose(self):
self.close()
return
def ComReset(self):
print "Executing ComReset function...!!"
self.write("~~~~~~~~~~\r")
i = 0
while i<10 :
response = self.readline()
print "Inside first while loop...!!"
print "response = "+response
if (response == ':'):
print "-->colon found...ready for next input<---"
break
i=i+1
time.sleep(0.5)
return
执行上述操作时,我收到以下错误
"Traceback (most recent call last):
File "C:\Users\vgupta\Desktop\KeyAT\final\WDEAutomationTestSuite\WDETestSuite\Bootguard\TC#001.py", line 17, in <modul
e>
obj.ComReset()
File "C:\Users\vgupta\Desktop\KeyAT\final\WDEAutomationTestSuite\APILib\ComLib.py", line 52, in ComReset
self.write("~~~~~~~~~~\r")
AttributeError: Com instance has no attribute 'write'"
任何人都可以帮助我找出问题所在。
谢谢, VIPUL
答案 0 :(得分:2)
self.sSerial = serial.Serial() self.sSerial.port = "COM1" self.sSerial.baudrate = 9600 .........
然后你可以self.sSerial.write("~~~~~~~~~~\r")
