Print a string in binary format

[neutrino]

Greetings to the Python gurus,

I have a binary file and wish to see the "raw" content of it. So I open
it in binary mode, and read one byte at a time to a variable, which
will be of the string type. Now the problem is how to print the binary
format of that charater to the standard output. It seems a common task
but I just cannot find the appropriate method from the documentation.
Thanks a lot.
