How to check if attribute exist in product attribute set?

I need to know if a product has an attribute for its set of attributes.

I get the attribute with:

$attrPricekg = Mage::getModel('catalog/product')->load($_product->getId())->getPricekg();

If attribut exist in product attribute set, $attrPricekg display: set value for the product
or 0 if no value set for the product.

If the attribute does not exist in product attribute set, $attrPricekg display 0. This is my problem.. I need to avoid this, I want to check that the attribute does not exist for that product.

Thanks.

now I'll provide an answer which works regardless!

$product = Mage::getModel('catalog/product')->load(16);

$eavConfig = Mage::getModel('eav/config');
/* @var $eavConfig Mage_Eav_Model_Config */

$attributes = $eavConfig->getEntityAttributeCodes(
    Mage_Catalog_Model_Product::ENTITY,
    $product
);

if (in_array('pricekg',$attributes)) {
    // your logic
}

Python – How to know if an object has an attribute in Python

Try hasattr():

if hasattr(a, 'property'):
    a.property

See zweiterlinde's answer below, who offers good advice about asking forgiveness! A very pythonic approach!

The general practice in python is that, if the property is likely to be there most of the time, simply call it and either let the exception propagate, or trap it with a try/except block. This will likely be faster than hasattr. If the property is likely to not be there most of the time, or you're not sure, using hasattr will probably be faster than repeatedly falling into an exception block.

Magento: template based on attribute set

No it doesn't but you can extend the functionality to do so by extending the _initProductLayout method in Mage_Catalog_ProductController under where the code is this

    $update = $this->getLayout()->getUpdate();
    $update->addHandle('default');
    $this->addActionLayoutHandles();

    $update->addHandle('PRODUCT_TYPE_'.$product->getTypeId());
    $update->addHandle('PRODUCT_'.$product->getId());

You could add

$update->addHandle('PRODUCT_ATTRIBUTE_SET_ID_'.$product->getAttributeSetId());

Then in your layout.xml you could have

<PRODUCT_ATTRIBUTE_SET_ID_IDHERE>
  <reference name="root">
            <action method="setTemplate"><template>template/path/here.html</template></action>
        </reference>
</PRODUCT_ATTRIBUTE_SET_ID_IDHERE>
