Question

What does this print: alist = ['a', 'b', 'c', 'd', 'e', 'f'] alist[1:3] = [] print(alist)

Answer 1

After executing the command alist[1:3] = [], elements 'b' and 'c' are removed from the original list. The new list printed will be ['a', 'd', 'e', 'f'].

Step-by-step explanation:

The student's question involves a list manipulation in Python programming. The given code is attempting to modify a list by removing a slice of its elements.

The line alist[1:3] = [] will remove the elements at index 1 and 2. In Python, list slicing is inclusive of the start index and exclusive of the end index. Given the original list ['a', 'b', 'c', 'd', 'e', 'f'], the slice [1:3] corresponds to elements 'b' and 'c'. After this operation, these elements are removed, resulting in the list ['a', 'd', 'e', 'f'].

So, when the list is printed with the print(alist) statement, the output will be:

['a', 'd', 'e', 'f']
