Identity Operator (is) vs Equality Check (==) Program Code

# Lists have identical values but different addresses
list1 = [1, 2, 3]
list2 = [1, 2, 3]
list3 = list1

# Comparing value equality
print("list1 == list2:", list1 == list2)

# Comparing identity (memory location check)
print("list1 is list2:", list1 is list2)
print("list1 is list3:", list1 is list3)

# Verify that list3 refers to list1
print("list3 == list1:", list3 == list1)
