Global accessing of parameter to class

[Mahamutha]

I need to access the variable from main.py to global_rrt.py. I need to access the variable serial_rrt_read in global_rrt.py under the calss frame_101.

global_rrt.py
global serial_rrt,serial_rrt_read           #Read data from RS232 port of fast charger
global serial_length                        #Determine the length of serial read from fast charger


from main import*
print serial_rrt_read
class frame_101:
        frame_101_serial =  "1111111100000000"
        frame_101_start  =  frame_101_serial[0:8]
        frame_101_f_id   =  frame_101_serial[8:16] 
        frame_101_end    =  frame_101_serial[632:640]

frame_101_data = frame_101()
#print frame_101_data.frame_101_serial

main.py
import time                     #Deals with date and time
#import serial                   #Acess for Serial Port
import subprocess               #Allows us to spawn processes
import os                       #Provides a way of using operating system dependent functionality
import sys                      #Access variables used or maintained by the interpreter
from global_rrt import*         #Access Global Variables in Main File

#Start Reading Serial Port Data
#serial_rrt = serial.Serial('/dev/ttyACM1', 9600, timeout=1)

while 1:
    #serial_rrt_read = ser.readline()
    serial_rrt_read = "1111111100000000"
    #print serial_rrt_read
    serial_length = len(serial_rrt_read)
    #print serial_length
    if(serial_length == 16):
        frame_101_data = frame_101()
        print "Hi"
        print frame_101_data.frame_101_serial
