Remove Last Element from Python List

Introduction

In Python, a list is a collection of items that are ordered and changeable. Sometimes, we need to remove the last element of a list and get all the other elements. In this challenge, you need to create a function that returns all the elements of a list except the last one.

List Initial

Write a Python function called initial(lst) that takes a list as an argument and returns all the elements of the list except the last one.

def initial(lst):
  return lst[:-1]

initial([1, 2, 3]) ## [1, 2]

Summary

To solve this challenge, you need to use Python's list slicing feature. The lst[:-1] syntax returns all but the last element of the list.
