Hi!
What is the best way to read a file that begins with some few text lines
and whose rest is a binary stream?
As an exmaple ... files .pnm.
Thanks for any comments/help on this.
Read the entire file in binary mode, and figure out which parts are
text and how they're encoded (possibly ASCII or UTF-8). Then take just
those snippets, and decode them. Something like this:
data = open("some_file", "rb")
You accidentally omitted the part where you read() the data
data = data.read()
text_part = data[2718:3142]
decoded_text = text_part.decode("utf-8")
That'll give you a usable Unicode string, assuming you have your
offsets and encoding correct.
