I meant to use that you can use struct.pack to create data that can be
interpreted as a structure defined in C, assuming the same architecture
is run on both machines.  Such sharing of data is one of the use cases
of the struct module.  For example:

# python side:
import struct
s = struct.pack('cid', 'A', 10, 20.0)
send_data_to_network(s)

/* C side: */
struct data_desc {
  char c;
  int i;
  double d;
};

char *s;
struct data_desc data;

s = read_data_from_network();
memcpy(&data, s, sizeof(data));
/* data.c is now the char
   data.i the int
   data.d the float (double) */

Hi, 
if you want to write and run C code in Python IDE with auto-completion
if you want to introspect into C functions and data structs 
if you hate the {} and ;  and the DOS window (console)
Please take a look at:
http://pythoidc.googlecode.com
PythoidC is the C language like the Python, by the Python and for the Python
 
import c
c.include(c.h.stdio) 
c.include(c.h.stdlib) 
'''Annotation is free!''' 
int fib(int n): 
    if(n<=2): 
        return1 
    else: 
        return fib(n-1)+ fib(n-2) 
int main(int argc,char**argv): 
    int n //C style annotation 
    n=c.stdlib.atoi(argv[1]) 
    c.stdio.printf('fibonacci(%d)=%d\n', n, fib(n))
