Converting Hexa to Binary from list

Im trying to open list with values and their hexa data and convert each line to only binary value (with small mask).

For example in my txt file I have:

DATA0 = 0x413e960d
DATA1 = 0x1c1c81c7
DATA2 = 0xa0000000
(32 Bits)

I want the output to be:

000000000000000001000001001111101001011000001101
000000000000000000011100000111001000000111000111
000000000000000010100000000000000000000000000000
(48 Bits)

I want to write those values in a new file, In my code for some reason, it skips the first value conversion, can you assist me with understanding why?

Code:

with open(input,'r') as r, open(output,'w') as w:
        #lines = r.readlines()
        
        for line in r:
            # if not line.startswith('#'):
            if line.startswith('DATA'):
                #print(line)
                new_line = line.rsplit("=")[1]
                new_line.strip()
                w.writelines(new_line)
                w.writelines(new_line + str( bin(int(new_line, 16))[2:] ).zfill(48))

I have also tried this conversion : (Last line)

        w.writelines(new_line + str('{:048b}'.format(int(new_line.strip(), 16))))

You're writing your hex values twice with inconsitent line breaks, but overall I see all values being converted. Try to simplify your code:

with open("file.txt",'r') as r, open("output.txt",'w') as w:
    for line in r:
        if line.startswith('DATA'):
            hex_val = line.rsplit("=")[1].strip()
            w.writelines(f"{hex_val}:\n{bin(int(hex_val, 16))[2:].zfill(48)}\n\n")

Output:

0x413e960d:
000000000000000001000001001111101001011000001101

0x1c1c81c7:
000000000000000000011100000111001000000111000111

0xa0000000:
000000000000000010100000000000000000000000000000

You forget to strip "\n" from line

with open("input.txt",'r') as r, open("output.txt",'w') as w:
    for line in r:
        line_without_white_characters_including_next_line = ''.join(line.split()) # removes whitespaces and \n
        if line_without_white_characters_including_next_line.startswith('DATA'):
            new_line = line_without_white_characters_including_next_line.split("=")[1]
            w.writelines(str( bin(int(new_line, 16))[2:] ).zfill(48))
            w.writelines("\n") # need to write next line so values are not next to each other

My output:

000000000000000001000001001111101001011000001101
000000000000000000011100000111001000000111000111
000000000000000010100000000000000000000000000000
