For example, I want to write 6277101735386680763835789423176059013767194773182842284081 to a file in binary in exactly 24 bytes (unsigned, I will only be working with positive integers). pack('5B', *newFileBytes)) However I would never give a binary file a . If you have actual integers you want to write as binary, you can use the bytes function to convert a sequence of integers into a bytes object: >>> lst = [7, 8, 7] >>> bytes(lst) b'\x07\x08\x07' Combining this, you can write a sequence of integers as a bytes object into a file opened in binary mode.
