If its not working, maybe your python is writing to standard error and not standard output. If this is the case you need to:

( python_script.py 2>&1 ) | C_program

It seems that you doing all right.

For example, if I need to redirect scripts output to program input, I used such construction:

$ my_script.py | progr

with case if progr accepts arguments in you code.

Redirection is done by the shell. As long as python script writes to stdout and C_program reads from stdin it should work ok.
