I am trying to read a binary log file to extract system counters. These

write a program in C to read and give the output as lists for use by
chart-director. If possible i would like to do the parsing of data only
once in C on the log file and pass the processed output for direct use
by python.
Wait..
Why not have Python read the binary log file itself, parse it and make
the API calls right there? Why do you even need the C program?
I have thought about having to populate a database first but will prefer
to avoid having another intermediate datastore (apart from the log file).
thanks,

Hi,
I am writing a script to read list output from a C executable.
How should c program be written so that python can read the
output as a list?
Any pointers to info on this appreciated.
The possibilities are truly wide open on this. Python can read a
variety of standard formats (and of course can have custom code to
read anything. Depending on what the data involved actually are,
you need to decide what format works best.
A simple approach is to have the C program write simple CSV output,
and use Python's csv module to read it. A more complex solution
might be to use XML. There are approximately 52,495,102 other
possibilities available too, so you have lots of room to work out
what's best for your application. More specific information on
what you're trying to accomplish would help narrow it down as well.
