In this article, we'll explain in detail when to use a Python array vs. a list. Mutable, 2. You can perform different types of operations on a list as per your requirements. Writing code in comment? List: A list is of an ordered collection data type that is mutable which means it can be easily modified and we can change its data values and a list can be indexed, sliced, and changed and each element can be accessed using its index value in the list. Empty lists vs. empty tuples. To get an even deeper look into lists, read our article on Python Lists. Python | Sort tuple list by Nth element of tuple, Python - Convert Tuple Matrix to Tuple List, Python | Replace tuple according to Nth tuple element, Python - Raise elements of tuple as power to another tuple, Python - Convert Tuple String to Integer Tuple, Python program to convert Set into Tuple and Tuple into Set, Python | Pair and combine nested list to tuple list, Python program to create a list of tuples from given list having number and its cube in each tuple, Python | Merge list of tuple into list by joining the strings, Python | Convert list to indexed tuple list, Python | Convert Integral list to tuple list, Python | Convert mixed data types tuple list to string list, Python | Convert List of Dictionary to Tuple list, Python - Convert Tuple value list to List of tuples, Python program to convert a list of strings with a delimiter to a list of tuple, Python | Count the elements in a list until an element is a Tuple, Python - Tuple key detection from value list, Python | Ways to iterate tuple list of lists, Python | Remove tuple from list of tuples if not containing any character, Data Structures and Algorithms – Self Paced Course. If you have a dataset which will be assigned only once and its value should not change again, you need a tuple. Both lists and arrays are used to store data in Python. The syntaxes of each one of these data structures are different. Python List Vs Tuple. It is easy to read and learn. Python Tuple is used for defining and storing a set of values by using (), which is the curly parenthesis. An array is an ordered collection of the similar data types. To install the python’s numpy module on you system use following command, pip install numpy. Tuples are immutable and can store any type of data type. If you really need to use a static array in your program, you should use tuple as it is better at memory management than an array and does the same job as a static array. Both List and Tuple are called as sequence data types of Python. In this article we will see various ways to do that. Immutable. Both these data types are very similar to each other but there are a few differences also. When creating an empty tuple Python points to already preallocated one, in such way that any empty tuple has the same address in the memory. Advantages of Python Sets Hope you like our explanation. Concatenation, repetition, indexing and slicing can be done on objects of both types This gives tuples speed advantage for indexed lookups and unpacking. very space efficient. An array is a contiguous memory allocation for data storage. A list has a variable size while a tuple has a fixed size. Therefore, it is a common language for beginners to start computer programming. The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values. Lists can be used to store any data type or a mixture of different data types. Unlike lists, tuples are immutable. The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values. Moreover, both data structures allow indexing, slicing, and iterating. Lists has variable length, tuple has fixed length. Unlike an array, a linked list is not continuous memory allocation. List has more functionality than the tuple. Strengthen your foundations with the Python Programming Foundation Course and learn the basics. Now that we know the differences between python tuples vs lists, it shouldn’t be a very tough choice between the two. I'll keep uploading quality content for you. Have a quick recap of data structures in Python with TechVidvan. Lists and Tuples store one or more objects or values in a specific order.
