(1, 2, 3, 4) Tuples are faster and consume less memory. Python has six built-in What they have in common is that they are used as data structures. C. [1] [1, 2] [1, 2, 3] D. 30 C. (‘Python’, ‘Python’) D. , A. Whereas List is the mutable entity. Lists are enclosed in brackets: l = [1, 2, "a"] Tuples are enclosed in parentheses: t = (1, 2, "a") Tuples are faster and consume less memory. Question: 2. D. random.shuffleList(fruit), A. A. The builtins data structures are: lists, tuples, dictionaries, strings, sets and frozensets. Python programs are easy to test and debug. Till then, enjoy reading and keep learning. But it’ll require a thorough understanding of these features and their usage. 1 2 3 4 5 6 The major key differences between Lists and tuples is that List is dynamic while tuple is static in nature Once Python has created a tuple in memory, it cannot be changed. [1] [2] [3] C. {‘a’:1,’b’:2} You can alter list data anytime in your program. A very fine explanation of Tuples vs List is given in the StackOverflow ans Apart from tuples being immutable there is also a semantic distinction that should guide their usage. The biggest difference between these data structures is their usage: Lists - for ordered sequence of objects. They may regurgitate (just not on the carpet...) that information at any point, and their bit of information can be changed at any time. Elements are accessed via numeric (zero based) indices. In Python, the most important data structures are List, Tuple, and Dictionary. Next, lists are mutable which you can modify after creation. In Python, the most important data structures are List, Tuple, and Dictionary. Difficulty Level : Easy; Last Updated : 10 Jul, 2020; 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. C. 98 97 96 And arrays are stored more efficiently (i.e. (‘Python’) Empty lists vs. empty tuples. Job Interview Question, When Do You Use List Vs. Tuple Vs. D. 2 3 4 5 6 6.

Key Error But the major difference between the two (tuple and list) is that a list is mutable, but a tuple is immutable. In order to create robust and well-performing products, one must know the data structures of a programming language very well. Tuple - can be considered as immutable list. Lists has variable length, tuple has fixed length.     {(1, 2): 12, (4, 2, 1): 10, (1, 2, 4): 8} Dictionary Vs. Set? In this post, we will s ee how these structures collect and store data as well as the operations we can do with them. A tuple is an assortment of data, separated by commas, which makes it similar to the Python list, but a tuple is fundamentally different in that a tuple is "immutable." [4, 3, 2] And if there is no difference between the two, why should we have the two? B. If the user wants to utilize the sequence as a dictionary key, a tuple is a better choice because dictionary keys are immutable. On the other hand, List is used for defining and storing a set of values by using the square brackets represented as []. I have used a Dictionary structure that will contain the int and list of tuple collection. Each of those values then becomes a field of the tuple.     {(1, 2): 12, (4, 2, 1): 10, (1, 2, 4): 8} Between these two structures are list, dict, tuples, and the Boolean field is.... 1,2 ] C. { ‘ a ’:1, ’ B ’:2 D....
