执行 Python 代码：
<?php
function test() {
return 'Test';
}
$py = <<<EOT
import phalcon
print phalcon.call('test')
print phalcon.call('sha1', ('tuple',))
print phalcon.call('sha1', ['list'])
EOT;
Phalcon\Py::exec($py);
导入模块：
<?php
$phalcon = Phalcon\Py::import('phalcon');
Phalcon\Py::callFunction($phalcon, 'call', 'test');
调用对象方法：
<?php
$list = Phalcon\Py::list([5,1,2,3,4]);
Phalcon\Py::callMethod($list, 'sort');
