5.1 Very High Level Embedding

</H1>

<P>
The simplest form of embedding Python is the use of the very
high level interface. This interface is intended to execute a
Python script without needing to interact with the application
directly. This can for example be used to perform some operation
on a file.

<P>
<div class="verbatim"><pre>
#include &lt;Python.h&gt;

int
main(int argc, char *argv[])
{
  Py_Initialize();
  PyRun_SimpleString("from time import time,ctime\n"
                     "print 'Today is',ctime(time())\n");
  Py_Finalize();
  return 0;
}
</pre></div>

<P>
The above code first initializes the Python interpreter with
<tt class="cfunction">Py_Initialize()</tt>, followed by the execution of a hard-coded
Python script that print the date and time.  Afterwards, the
<tt class="cfunction">Py_Finalize()</tt> call shuts the interpreter down, followed by
the end of the program.  In a real program, you may want to get the
Python script from another source, perhaps a text-editor routine, a
file, or a database.  Getting the Python code from a file can better
be done by using the <tt class="cfunction">PyRun_SimpleFile()</tt> function, which
saves you the trouble of allocating memory space and loading the file
contents.
