This tutorial will guide you through a simple, yet crucial aspect of Python, which is renaming a list. Renaming a list is a necessity in Python programming particularly when managing data and certain values need to be replaced with something more appropriate or user-friendly.
This task doesn’t directly exist in Python’s built-in functions but can be easily accomplished by assigning the old list to a new name.
Step 1: Create a List
Create a list in Python. A list is a collection of items that are ordered and mutable. They are represented in enclosed square brackets []. For this tutorial, we will name our list old_list and give it four elements: “Apple”, “Banana”, “Cherry”, “Date”.
1 2 |
old_list = ["Apple", "Banana", "Cherry", "Date"] print(old_list) |
Output:
["Apple", "Banana", "Cherry", "Date"]
Step 2: Rename the List
Renaming the list is as straightforward as assigning the old list to a new name. This is done by specifying the new name followed by an equals sign and the name of the old list. For instance, if we had named our list old_list and wanted to rename it to new_list, we would do the following:
1 |
new_list = old_list |
Step 3: Verifying the List Renaming
To confirm that the list renaming performed the intended operation, print the new list.
1 |
print(new_list) |
If you run the above code, the new_list will produce the same output as the old_list.

Here is the full block of the code:

old_list = ["Apple", "Banana", "Cherry", "Date"] print(old_list) new_list = old_list print(new_list) |
Output:
["Apple", "Banana", "Cherry", "Date"] ["Apple", "Banana", "Cherry", "Date"]
Conclusion
This tutorial demonstrates how to rename a list in Python. As discussed, renaming a list in Python doesn’t exist as an inherent function. But this context is still achievable by assigning the old list to a new name. This feature is particularly useful in cases where you need to change variable names on the fly without altering the content of the list.
