read a binary file (python)

hope this fix your issue That is the binary. They are stored as bytes, and when you print them, they are interpreted as ASCII characters.
You can use the bin() function and the ord() function to see the actual binary codes.

for value in enumerate(data):
   print bin(ord(value))

Hope that helps , bytes is an alias for str in Python 2.7

wish of those help I use this piece of code: , This format is not correct:

author_name, nu_of_publ = read_chunk(str(len_author_name)+'si', f)

struct {
    char author_name[N];
    int nu_of_publ;
};

author_name = read_chunk(str(len_author_name)+'s', f)
nu_of_publ, = read_chunk('i', f)

author_name, nu_of_publ = read_chunk('={}si'.format(len_author_name), f)

may help you . The newer revisions of ISO 7816, part 4 offer an odd INStruction variant (i. e. INS=0xB1), where one has to supply an offset DO (tag 0x54) in the command data field. Fortunately the length of this DO is variable, so really big offsets can be specified. The odd instruction commands have still an exotic touch however, where no strict specification asks for them, but surely a card supporting large files will likely support this instruction variant too.
The only fallback I'm aware of is specifying 0x7FFF as starting offset and as large an (extended length) LE as the card permits, but this may be insufficent for significantly larger files.

I wish this help you I have a binary file, which is *.xyz, a binary plot3d format file. I don't know how to read it from python. I got no problems to open a txt counterpart of it, but how can I open this binary directly? , OK, I solved the problem by myself, using FortranFile module:

from scipy.io import FortranFile

read_ints()
read_reals()
