How is List Different From Tuple

How is List Different From Tuple

Edited By Team Careers360 | Updated on Mar 23, 2022 11:34 AM IST

List and tuple are data structures in Python that can store one or more objects or values. Using square brackets, you may create a list to hold numerous objects in one variable. Tuples, like arrays, can hold numerous items in a single variable and are declared with parenthesis. Although list and tuple have numerous differences, they also have certain parallels, as shown below:

Both data structures are sequence data types, which store groups of things.

  • Any type of data can be stored in them
  • The index can be used to find items

For a better understanding, the following sections present a fuller description of list vs tuple.

1. Syntax differences

The syntax for list and tuple differs, as stated in the introduction. Consider the following scenario:

list_num = [10, 20, 30, 40]

tup_num = (10, 20, 30, 40)

2. Mutability

The distinction between a list and a tuple is that a list is mutable, whereas a tuple is immutable. This means that lists can be modified while tuples cannot. As a result, some operations on lists are possible, but not on tuples. In data science, for example, if a list already exists, specific pieces of it can be reassigned. The full list can also be reassigned as a result of this. The list can be cleaned up by removing elements and slices of elements. Individual items on the tuple, on the other hand, cannot be reassigned or deleted, but the tuple as a whole can be reassigned and destroyed. Tuples cannot be copied since they are immutable.

3. Operations

Even though lists and tuples have many operations in common, lists offer additional features that tuples do not. Insert and pop operations, as well as sorting and removing elements from a list, are all included.

4. Functions

Some Python functions, such as len, max, min, any, sum, all, and sorted, can be used on both data structures.

5. Differences in Representation

Lists and tuples have slightly different representations. The square bracket [] is widely used to denote a list, and elements are comma-separated items. The comma separates components, and parenthesis () is used to enclose them. The usage of parenthesis is optional, and these tuples are known as tuple packing.

6. Size

Tuples are allocated huge blocks of memory with minimal overhead in Python because they are immutable, whereas lists are assigned small memory chunks. Tuples have the smallest memory of the two. When there are a high number of elements, this makes tuples faster than lists.

7. Elements' types

Tuples are used to hold elements that belong to distinct data types, or heterogeneous elements. Lists are used to store homogeneous elements or elements of the same data type. This, however, is not a limitation for data structures. Tuples can be used to store similar data type components, and lists can be used to store diverse data type elements.

8. Length

The two data structures have different lengths. Lists have variable lengths, but tuples have a set length. As a result, the size of constructed lists can be adjusted, but not for tuples.

9. Debugging

When it comes to debugging, tuples are easier to debug for large projects than lists because of their immutability. So, if you have a smaller project or a smaller amount of data, lists are a better option. Because lists can be modified but tuples cannot, tuples are easier to keep track of.

10. Tuples and nested lists

Lists can be stored inside tuples, and tuples can be stored inside lists. A tuple can hold multiple tuples in nested tuples. In nested lists, a list can include many lists.

11. Uses

It's vital to realize that there are a variety of situations in which one of these data structures is preferable, such as when the programmer must choose between the two based on whether they wish to update the data later or not. Tuples can be used to store data in the same way that a dictionary without keys can. It is easier to read data when tuples are stored in lists.

Final Takeaway!

The differences between lists and tuples are explained in this article. Even though both kinds are data structures in Python, it is vital to understand the distinctions before making a decision. The most significant distinctions to remember are that lists are mutable whereas tuples are not and that lists have variable sizes while tuples do not. Finally, tuple operations can be performed more quickly. If you're reading this, you probably want to work as a Python developer.
