Which method is used to remove and return the last element from an array in Python?Optionspop()remove()delete()discard()

The method used to remove and return the last element from an array in Python is pop(). Here's how you can use it:

1. First, you need to have an array. For example, let's create an array named 'arr':

arr = [1, 2, 3, 4, 5]

2. Then, you can use the pop() method to remove and return the last element from the array. By default, pop() removes the last element but you can also specify the index of the element to remove.

last_element = arr.pop()

3. Now, 'last_element' contains the value 5, which was the last element in the 'arr' array. And 'arr' now contains [1, 2, 3, 4].

Note: The other methods mentioned in the options, remove(), delete(), and discard(), are not used to remove and return the last element from an array in Python. The remove() method removes the first occurrence of a value, delete() is used in numpy arrays to remove elements from a specific axis, and discard() is used in sets to remove an element if it is present.
