Final answer:
The code uses list slicing in Python to copy the entire 'numbers' list into 'my_list' and then prints it, which will display '[1, 2, 3, 4, 5]'.
Step-by-step explanation:
The code in question is a simple Python program dealing with list slicing and printing. When the slice operator [:] is used with no specific start or end, it creates a shallow copy of the original list. Thus, the variable my_list will be a new list that contains the same elements as numbers.
Therefore, the output of the code will be:
[1, 2, 3, 4, 5]
This output represents the entire list from numbers because the slice copied all elements.
