beginner in python

[Beema shafreen]

Hi everybody ,
      I am a beginner in python,
         I have to fetch the redundant entries from a file,

code:

import re
L = []
fh = open('ARCHITECTURE_MAIN.txt','r')
for line in fh.readlines():
        data =line.strip()
#       splitted = data.split('#')
        L.append(data)
fh.close()


M=L
for x in L:
        x = x.split('#')
        for y in M:
            y = y.split('#')
        x_data = x[0],x[1],x[2],x[3]
        #print x_data
        y_data = y[0],y[1],y[2],y[3]
        #print y_dat
        if x_data[0] == y_data[0]:
              print x_data


i get the result as a tupule,
the text file which has datas separated by hash
entry#isoform#start#stop#  i have to check upto this
