संभव डुप्लिकेट:

हाई,

एक ऑब्जेक्ट डालना कब और कब "ऐज़" का उपयोग करना है।

उदाहरण:
class a = (class ) वस्तु
और वर्ग ए = वस्तु के रूप में वस्तु का उपयोग करने के लिए

के रूप में का उपयोग करना एक सुरक्षित विकल्प है, जैसे कि कास्ट विफल रहता है, आपको कोई अपवाद नहीं मिलता है, लेकिन लौटाया गया मान null है। < / P>

यदि कोई कलाकार संभव नहीं है, तो आप अपवाद पाने के लिए चाहें () का उपयोग करें।

This will allow dragon to search your modules (otherwise, Python looks for the .py module).
