Identity operators are used to compare the objects, not if they are equal, but if they are actually the same object, with the same memory location:

Operator	Description	Example	Try it
is	Returns True if both variables are the same object	x is y	Try it »
is not	Returns True if both variables are not the same object	x is not y	Try it »

Examples

python

val_1 = ["apple", "banana"]
val_2 = ["apple", "banana"]
z = val_1

print(val_1 is z)
print(val_1 is val_2)
print(val_1 == val_2)

python

val_1 = ["apple", "banana"]
val_2 = ["apple", "banana"]

print(val_1 is not val_2)

python

val_1 = [1, 2, 3]
val_2 = [1, 2, 3]

print(val_1 == val_2)
print(val_1 is val_2)
