Modify Python List Elements and Create Empty Dictionary

How can we modify a Python list to contain specific elements?

Which command is used to remove the last element of a list and create a new list with specific elements?

Answer:

The command x = x[:4] results in the list x containing the elements [1, 2, 3, 4].

To modify a Python list to contain specific elements, we can use the slicing technique. In this case, the command x = x[:4] creates a new list by slicing the first four elements from the original list x and assigns it back to x. This results in x containing only the elements [1, 2, 3, 4].

By using slicing, we can easily manipulate lists and extract specific subsets of elements without modifying the original list directly. It's a powerful feature in Python that allows for efficient list operations.
