In this article we will show you the solution of python empty list of size n, an empty list is a sort of data structure in Python that can hold several elements of any kind. It offers a method for effectively organising and working with data.

Although an empty list by definition has no elements, it is possible to construct an empty list of a particular size.

You can initialise an empty list of size n with a predetermined number of placeholders, like None, or any other value that meets your needs.

This enables you to set aside room in the list for n elements, even if they haven't been assigned.

When you know ahead of time how many elements the list will eventually contain, having an empty list of size n can be helpful.

It offers a framework that can dynamically expand or change as new elements are added or old ones are eliminated. We'll talk about the concept of a Python empty list of size n now.

Step By Step Guide On Python Empty List Of Size N :-

n = 5 # Specify the desired size of the list
empty_list = [None] * n # Create an empty list of size n
# Print the initial empty list
print("Initial empty list:", empty_list)
# Assign values to the list
for i in range(n):
    empty_list[i] = i + 1
# Print the modified list
print("Modified list:", empty_list)
# Append new elements to the list
empty_list.append(6)
empty_list.append(7)
# Print the list after appending
print("List after appending elements:", empty_list)
# Remove elements from the list
empty_list.remove(3)
empty_list.remove(6)
# Print the list after removal
print("List after removing elements:", empty_list)

1. We begin by utilising the variable n to indicate the required list size.
2. The value of None is then multiplied by n to generate an empty list, which is named empty_list.
3. This produces a list with n entries, all of which start out set to None.
4. To display the initial empty list, we employ the print() method.
5. We may see the list's initial state by writing "Initial empty list:" and then the value of the variable empty_list.
6. Then, using a for loop, we iterate across the range of n.
7. We give a value to each element of empty_list after each iteration.
8. By utilising the index i to access the entries, we assign the value i + 1 to guarantee that the list contains only consecutive numbers beginning with 1.
9. We use the print() function once more to display the changed list after assigning the values.
10. We may see the list's modified values by writing "Modified list:" after the variable empty_list.
11. Using the append() method, we show how to add new entries to a list.
12. Call it empty_list.empty_list and append(6).append(7) will append the numbers 6 and 7 to the end of the list, respectively.
13. We once more make use of the print() function to display the list after adding.
14. We may see the list with the newly added elements by displaying "List after appending elements:" and then the variable empty_list.
15. Next, we demonstrate how to use the remove() method to remove elements from a list.
16. To remove the members from the list that have values of 3 and 6, respectively, we call empty_list.remove(3) and empty_list.remove(6).
17. The print() function is then used to print the list after it has been removed.
18. Printing "List after removing elements:" and the variable empty_list afterward allows us to see the list with the given elements deleted.

Conclusion :-

As a result, we were able to understand the idea of a Python empty list of size n.

A list with a certain number of elements can be created using the idea of an empty list of size n, even if the members are initially uninitialized or assigned to a placeholder value.

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