That's still too vague to be meaningful. Just reading a file
seems pointless:
cat foo >/dev/null
Here, "cat" is a C program that "opens and reads" the file
named foo.

So you want the data returned to your Python program? If so,
you can't just execute a C program. If you want to use the
data in the file, you have to read the data from _somewhere_.
You can read it directly from the file, or you can read it from
a pipe, where it was put by the program that read it from the
file. The former is going to be far, far faster.
