x = ["apple", "banana"]
y = ["apple", "banana"]
z = x
​
print(x is not z)
​
# returns False because z is the same object as x
​
print(x is not y)
​
# returns True because x is not the same object as y, even if they have the same content
​
print(x != y)
​
# to demonstrate the difference betweeen "is not" and "!=": this comparison returns False because x is equal to y
