Having a hard time conceptualizing how to print something

[MysticLord]

In line 12, inside the right parenthesis add

end = ''

Useless in this context as I'm trying to transpose a matrix, apparently. If I were just trying to print one row as a column your solution would be perfect, but I'm not.

How do I create a list of lists? This doesn't work.

import io,sys

with open(sys.argv[1], 'rb') as scus:
    baseAddr =58364 
    with open("sparks.txt", 'w') as writer:
        scus.seek(baseAddr)
        tblList1 = []
        cntr = 0
        while cntr < 16:
            tblList1.append(scus.read(16))
            cntr += 1

I wrote code whose output must be seen to be believed.

Code 1:

import io,sys

with open(sys.argv[1], 'rb') as scus:
    baseAddr =58364 
    scus.seek(baseAddr)
    with open("sparks.txt", 'w') as writer:
        tblList1 = []
        cntr = 0
        while cntr < 16:
            tblList1.append(scus.read(16))
            #tblList1.insert(cntr, scus.read(16))
            cntr += 1
            for i in tblList1:
                for j in i:
                    print(hex(j)[2:].zfill(2) + "-", end='')
                print()

Output 1:

Code 2:

import io,sys

with open(sys.argv[1], 'rb') as scus:
    baseAddr =58364 
    scus.seek(baseAddr)
    with open("sparks.txt", 'w') as writer:
        tblList1 = []
        cntr = 0
        while cntr < 16:
            #tblList1.append(scus.read(16))
            tblList1.insert(cntr, scus.read(16))
            cntr += 1
            for i in tblList1:
                for j in i:
                    print(hex(j)[2:].zfill(2) + "-", end='')
                print()

Output 2:

I don't know if it's a "feature" of lists in Python, or something to do with the read() method used in binary mode, but it's apparently adding redundant lines over and over again. What should be a 16x16 list becomes a 138x16 list.

Disregard, I am a moron. Here's the fixed code:

import io,sys

with open(sys.argv[1], 'rb') as scus:
    baseAddr =58364 
    scus.seek(baseAddr)
    with open("sparks.txt", 'w') as writer:
        tblList1 = []
        cntr = 0
        while cntr < 16:
            #tblList1.append(scus.read(16))
            tblList1.insert(cntr, scus.read(16))
            cntr += 1
        for i in tblList1:
            for j in i:
                print(hex(j)[2:].zfill(2) + "-", end='')
            print()
