I've found some really strange behaviourbehavior in Python. One of my students made some kind of mistake trying to find elements which belong to two lists :, he wrote:
list1 and list2
list1 and list2 The strange behaviourbehavior is that no error is fired by Python3 Python 3! list1 and list2list1 and list2 actually has got a value which is list2list2.
Is there any known reason for this ?
