Printing bytes from a serial port using python

[stopgo]

Hi forum,

I've looked at information coming from some equipment, and this is its output:
"&DELUX,58.0,10"
"&DELUX,58.5,10"
"&DELUX,59.0,10"
"&DELUX,59.5,10"
....

I would like to use Python v2.5.4 to receive this data, and pull out the 'E' to do further processing. This is my code:

import time
import serial

ser = serial.Serial(
                            port=0,
                            baudrate=9600,
                            bytesize=8,
                            stopbits=1,
                            timeout=0
                           )
while 1:
            data = ser.read(5)
             if data[2] == 'E':
                         print data[2]
             else:
                      print 'Error'

Unfortunately (for me), all I get printed is 'Error', which means Im trying to extract that byte in the wrong way.

Could anyone kindly point me in the right direction. This is getting a bit frustrating


Update:
So I figured out my problem. I was searching for an 'e' instead of 'E'. problem solved.

I've since modified my code and it all works fine. my new code:

import time
import serial

ser = serial.Serial(
                            port=0,
                            baudrate=9600,
                            bytesize=8,
                            stopbits=1,
                            timeout=0
                           )
while 1:
            data = ser.read(14)
             if data[0] == '&':
                         print data[7:10]
             else:
                      print 'Error'

My new question:
Is there a faster (more efficient) way of executing my new code ?

much thanks in advance.
