Take this for what it's worth.  If I understand correctly, you want
this:

struct info {
  char* name;
  char* address;
  int age;
};

int main( ) {
  info A, B;
  python_run( "\
from urllib import urlget\n\
from mylib import populate_struct\n\
page= urlget( 'http://something' )\n\
populate_struct( page, A )\n\
populate_struct( page, B )\n" );
  if( A.age> B.age ) {
    something_in_C( );
  }
  return 0;
}

Am I on the right track?  Do you have any questions so far?
