Question

In python, how do I read a binary file (here I need to read a .chn file) and show the result in binary format?

Answer 1

Assuming that values are separated by a space:

with open('myfile.chn', 'rb') as f:
    data = []
    for line in f:  # a file supports direct iteration
        data.extend(hex(int(x, 2)) for x in line.split())

In Python is better to use open() over file(), documentation says it explicitly:

When opening a file, it’s preferable to use open() instead of invoking
the file constructor directly.

rb mode will open the file in binary mode.
