Hi Anubhav, Ah! The assert functions are meant to be used as statements, not as composable expressions. If you're familiar with the idea of side effects, then you need to understand that you should be calling the assert functions just for their side effects, not for their return value. If you want to test two conditions, do them as separate statements. By trying to compose them with 'and', the code actually means something different due to boolean logic short circuiting. If you have questions, please feel free to ask. Good luck! _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
