list1 = [6,7,8]
list2 = [6,7,8]
print(list1 is list2)
This returns False acccording to your terminal. I don’t understand why. Shouldn’t it return True? If all the elements of two lists are the same, are they not the same lists? Thank you for any explanation.
Hi @Hajnalka_Toth,
Yes, all elements in the two lists are the same plus in the same order, but why does it return False?. Well, you might have noticed that there’s a is keyword in the print() statement. And what that does is “matches the references (not the values/elements) of those two lists”!
list1 and list2 are created on different memory locations, which is why the print(list1 is list2) returns False, which should be the expected output.
Note: If you change
list1 is list2tolist1 == list2, then you would get aTruevalue because the “==” operator compares the values of these two lists.
Thank you so much, and hope this helps.
Thank you so much for the quick response. Yes, that definitely helps, I guess I just wasn’t clear on what “comparing the references” meant! I understand now, thank you again!
