list1=[24, 28, 47, 53, 12]
print(list1[0:4:2])
print(list1[1:3])
print(list1[2:4])
print(list1[:-3])
print(list1[-1:])
print(list1[:])

The output of the preceding code would be as follows:

Output
[24, 47]
[28, 47]
[47, 53]
[24, 28]
[12]
[24, 28, 47, 53, 12]

LIST METHODS
To make the use of lists easier, Python provides various built-in methods. These methods are
associated with list objects and are called using the dot (.) notation.

Python has the following various built-in list methods:
append(): It adds a single item to the end of the list.

extend(): It adds all items from another iterable to the list.
insert(): It inserts an item at a specified index.

remove(): It removes the first occurrence of a specified item.
pop(): It removes and returns the item at the given index (last item by default).

clear(): It removes all items from the list.
index(): It returns the index of the first occurrence of a specified value.

count(): It returns the number of times a value appears in the list.
sort(): It sorts the list in ascending order by default.
reverse(): It reverses the order of the list.

copy(): It returns a copy of the list.
