PYTHON: Identity Operators
Identity operators are used to compare the objects. They do not just compare if they are equal, but if they are actually the same object, with the same memory location.
| Operator |
Description |
| is |
Returns true if both variables are the same object x is y
x = ["apple", "banana"]
y = ["apple", "banana"]
z = x
print(x is z)
# returns True because z is the same object as x
print(x is y)
# returns False 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" and "==": this comparison returns True because x is equal to y
|
| is not |
Returns true if both variables are not the same object x is not y
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
