Code:
g = [1, 2, 3]
h = [1, 2, 3]
print(g is h)
print(g == h)
Solution and Explanation:
In Python, the expressions g = [1, 2, 3] and h = [1, 2, 3] create two separate list objects that contain the same elements. When we use print(g is h) and print(g == h), we are comparing these two lists in different ways.
g is h
The is operator checks for object identity. It returns True if both operands refer to the exact same object in memory.
g = [1, 2, 3]
h = [1, 2, 3]
print(g is h)
In this case, g and h are two different objects that happen to have the same contents. Since they are distinct objects, g is h will return False.
g == h
The == operator checks for value equality. It returns True if the operands have the same value, which for lists means that they have the same elements in the same order.
g = [1, 2, 3]
h = [1, 2, 3]
print(g == h)
Here, g and h have the same elements in the same order, so g == h will return True.
Summary
g is h: Checks if g and h are the same object in memory (identity). Result: False.
g == h: Checks if g and h have the same contents (equality). Result: True.
Thus, the output will be:
False
True
