I have a text file having hex numbers which is meant for my matrix data.
The first line denotes the rows and cols of my matrices.
This is my input data

00080008 #Rows=0x0008 n cols=0x0008
0024FFF2 #LSB1
004AFFB6 #MSB1

My code needs the following:
the rows and coloumn line needs to be filled with "0"s to make it 128 bits
the lines following this line (cols + (rows * cols)+ 1) = 8 + 64 + 1 = 72 lines needs to be merged 4 lines at a time.

I need to combine 4 lines from here and make a hex value MSB2+LSB2+MSB1+LSB1

I have written a code for a pattern which repeats twice but due to some changes in the Master code i get the pattern repeating more than 2 times..How can i modify my code to take care of the repeating pattern?

What I have tried:

with open (filename, 'r') as f1:
    line_values=[line.strip() for line in f1]
f1.close()
width = line_values[0]
width = int(width,16)
rows = (width & 0xffff0000)>>16
cols = (width & 0x0000ffff)
print rows
print cols
counter = cols + (rows * cols) + 1
print counter
data_1 = line_values[:counter]
data_2 = line_values[counter + cols:- cols]

mem_file.write(line_values[0].zfill(32)+"\n")
index = 1

for i in range(int(counter/4)):
    mem_file.write("".join(data_1[(index + 3):(index-1):-1]))
    mem_file.write("\n")
    index += 4
mem_file.write(line_values[counter + rows].zfill(32)+"\n")
index = 1
for i in range(int(counter/4)):
    mem_file.write("".join(data_2[(index + 3):(index-1):-1]))
    mem_file.write("\n")
    index += 4

my data_1 and data_2

This code perfectly works for any pattern repeating twice. As i split the data into 2 lists and then use these lists items to combine and write in my txt file. How do I modify the code if the pattern repeats n number of times?

It "sounds" like it should be easy, but I don't think anybody understands what you want or what you're doing or what the point is.

try:
		with open (filename, 'r') as f1:
			line_values=[line.strip() for line in f1]
		f1.close()	
		# print len(line_values)
		index = 0
		while index < len(line_values):
			
			count = line_values[index]
			width = line_values[index]
			width = int(width,16)
			rows = (width & 0xffff0000)>>16
			cols = (width & 0x0000ffff)
			counter = cols + rows * cols + rows
			mem_file.write(count.zfill(32)+"\n")
			
			index += 1
			data_count = counter - rows
			# print data_count
			for i in range(int(data_count / 4)):
				mem_file.write("".join(line_values[(index + 3):(index-1):-1]))
				mem_file.write("\n")
				index += 4
			index += rows
				
		print "Done"
