Empty List In Python

Empty List In Python

In this article we will show you the solution of empty list in python, lists can be used in Python to hold several things in a single variable. One of the most used data structures in Python programming is this one.

You might occasionally have to initialize a list with no elements. Empty lists play a role in this situation.

Learn about empty lists, how to make them, and how to use them in Python in this tutorial.

We will begin by going over what empty lists are and how Python uses them.

Then, we'll go through the process of making empty lists and populating them with items.

We'll then look at some typical operations that can be applied to empty lists, like adding, extending, and removing members. We'll finish up by summarizing all we've learned about empty lists.

Step By Step Guide On Empty List In Python :-

# Creating an empty list
my_list = []
# Adding elements to an empty list
my_list.append("apple")
my_list.append("banana")
my_list.append("cherry")
# Accessing elements in an empty list
print(my_list[0]) # Output: "apple"
# Removing elements from an empty list
my_list.remove("banana")
print(my_list) # Output: ["apple", "cherry"]
# Extending an empty list with another list
my_list2 = ["orange", "grape"]
my_list.extend(my_list2)
print(my_list) # Output: ["apple", "cherry", "orange", "grape"]
# Clearing all elements from an empty list
my_list.clear()
print(my_list) # Output: []
  1. Making an empty list: By giving a variable a pair of empty brackets, we make an empty list. By setting it equal to a pair of empty brackets in the code block above, we were able to create the empty list "my_ list".
  2. Including items to an empty list : The "append()" method can be used to add elements to an empty list. By executing the "append()" method and supplying each element as a parameter, the "apple," "banana," and "cherry" elements were added to our empty list in the code block above.
  3. Getting to items in an empty list: Indexing allows us to get to elements in an empty list. The first element in our list, "apple," was retrieved in the code block above by using "my _list[0]".
  4. Removing items from a list that is empty: The "remove()" method can be used to remove items from a list that is empty. By using "my_ list. remove("banana")" in the code block above, we eliminated the element "banana" from our list.
  5. Adding another list to an empty one: Using the "extend()" technique, we can add another list to an empty one. The code block above built a new list called "my_list2" and then called "my_ list. extend(my_list2)" to add it to the original list.
  6. Eliminating every item from an empty list: The "clear()" method can be used to remove every element from an empty list. By using "my_ list .clear()" in the code block above, we removed every element from our list.

Conclusion :-

We have learnt what empty lists are in this tutorial, how to make them, and how to operate on them.

When you need to build a list without any elements, empty lists come in handy. They are simple to edit by adding or removing elements.

You can create Python programs that employ this crucial data structure more effectively if you know how to work with empty lists.

I hope this article on empty list in python helps you and the steps and method mentioned above are easy to follow and implement.
