In Python, there are numerous methods available for the list data type that help you eliminate an element from a given list.

Remove last element from list using pop()

The pop() method removes the element at the specified index position. The syntax of the pop() method is:

list.pop(index)

Here, the index is optional that specifies the position of the element you want to remove. By default, it removes the last element from the list. Here is the example-

list_elems = [43, 45, 89, 29, 30, 63, 10]
# Remove last element from list
list_elems.pop()
print(list_elems)

Output of the above code - 

[43, 45, 89, 29, 30, 63]

Remove last element from list using del statement

In Python, del is a keyword. We can use this del keyword to delete any objects, like lists, variables, user-defined objects, items within lists, dictionaries and so on. The syntax of the del is-

del obj_name

To delete the last element from a list, apply negative indexing to the list, and offer it to the del keyword to erase it.

list_elems = [21, 65, 38, 12, 22, 31, 19]

# Remove last element from list
del list_elems[-1]

print(list_elems)

Output of the above code - 

[21, 65, 38, 12, 22, 31]

Remove last element from list using slicing

We can also use slicing to remove the last element from the list. In this, we can get a part of it using Python slicing operator. The syntax of slicing is -

[start : stop : steps]

It means the slicing starts from the start index and goes up to stop in a step of steps. Here is the example-

list_elems = [30, 21, 19, 11, 52, 71, 20]

# Remove last element from list

print(list_elems[:-1])

Output of the above code - 

[30, 21, 19, 11, 52, 71]
