python is

The is keyword is used to test if two objects refer to the same object.

Here is what the above code is Doing:
1. It creates a list called my_list and assigns it the value [1, 2, 3]
2. It creates another list called your_list and assigns it the value [1, 2, 3]
3. It then tests if my_list is equal to your_list
4. Since my_list and your_list are equal, the code prints out “True”

5. It then tests if my_list is the same object as your_list
6. Although my_list and your_list are equal, they are not the same object, so the code prints out “False”
