Introduction
In our previous articles, we have discussed Lists and Tuples. Both terms have the same purpose of storing the data with a different nature. Then the question that arises here is what is the difference between a list and a tuple in Python? And why is it necessary to know the difference between a list and a tuple in Python? Lists are used to store dynamic values whereas Tuples can store static values. In real life, we need to store the data in two ways. In the first way, we store the data in a data structure and later access the data and perform operations on the data. For example, the name of the students. We can store the names in a list and can access the names, insert new names, and delete particular names. In the second way, we store the data in a data structure and can access the data only without modifying the data. For example, the name of topper students for a particular year. We can store the topper names in a tuple because once declared, the names will not alter, we can only access the names. So, this is the basic difference between a list and a tuple in Python. In this article, we will take a deeper look at the difference between Lists and Tuples in Python with an example.
Tuple vs List in Python
List and tuples in Python are data structures. Both terms in Python are known as a collection of elements where each element is assigned a unique number known as an index. Entries in the Python List/Tuples are known as elements or items. The main difference between List and Tuple in Python is, Python Lists are ordered and mutable. Whereas Python Tuples are ordered and immutable. Once we declare a tuple it cannot be modified or updated. When we talk about Tuple vs List in Python both are the data structures used to store the multiple values under a common name. Lists in Python are dynamic in nature but Tuples are static. Modification of the data inside the list is possible but we cannot modify the data inside the tuple because tuples are immutable. Tuples can be used in a situation where you don’t want to alter the data. This is all about Tuple vs List in Python. Let’s take a deeper look into the difference between List and Tuple in Python.
Difference between List and Tuple in Python with examples
Parameters | Lists in Python | Tuples in Python |
Nature | Mutable or changeable | Immutable or cannot change |
Iteration | Iterating through Lists is time-consuming | Iterating through Tuples is not time-consuming |
use | Good for insertion-deletion | Good for accessing elements |
memory | Requires more memory as compare to Tuples | Requires less memory as compared to Lists |
deletion | The List can delete any particular element | Tuples cannot delete elements rather it can delete a whole tuple |
creation | To create a List we can use the following waysdemo_List = [ ] #empty Listdemo_List = [1,2,3,4] #List with integer valuesdemo_List = ['Ram', 'Sham', 'Siya'] #List of strings | To create a Tuple we can use the following ways#Python Tuple exampledemo= ( ) #empty Tupledemo=(1, ) #Tuple with a single elementdemo= (1,2,3,4) #Tuple with integer valuesdemo= ('Ram', 'Sham', 'Siya') #Tuple of strings |
accessing elements | To get an entry from the List we use index numbers of the List. See the following example for more details:demo_List = ['Ram', 'Sham', 'Siya'] #List of stringsprint (demo_List [0]) # access the first elementprint (demo_List [1]) # access the second elementprint (demo_List [2]) # access the third elementOutput:RamShamSiya | To get an entry from the Tuple we use index numbers of the Tuple. See the following example for more details:demo_List = ['Ram', 'Sham', 'Siya'] #Tuple of stringsprint (demo_Tuple [0]) # access the first elementprint (demo_Tuple [1]) # access the second elementprint (demo_Tuple [2]) # access the third elementOutput:RamShamSiya |
Summary
In this article, we discussed Python Tuples vs Lists and the difference between List and Tuple in Python with examples. Python lists are dynamic in nature whereas tuples are static in nature. We can access and modify the elements stored inside the list but we can only access the elements stored in a tuple and cannot modify the elements. We hope you enjoyed the article.
