What is the difference between list and tuple give example?
Tuple is also a sequence data type that can contain elements of different data types, but these are immutable in nature. In other words, a tuple is a collection of Python objects separated by commas.
Difference Between List and Tuple in Python:
| SR.NO. | LIST | TUPLE |
|---|---|---|
| 1 | Lists are mutable | Tuples are immutable |

What is the difference between list tuple and set?
Sets vs Lists and Tuples
Lists and tuples are standard Python data types that store values in a sequence. Sets are another standard Python data type that also store values. The major difference is that sets, unlike lists or tuples, cannot have multiple occurrences of the same element and store unordered values.
Which is better list or tuple?
Tuples are faster than lists.
Some tuples can be used as dictionary keys (specifically, tuples that contain immutable values like strings, numbers, and other tuples). Lists can never be used as dictionary keys, because lists are not immutable.
What is the difference between list tuple and dictionary in Python?
List and tuple is an ordered collection of items. Dictionary is unordered collection. List and dictionary objects are mutable i.e. it is possible to add new item or delete and item from it. Tuple is an immutable object.
Why tuple is faster than list?
Tuple has a small memory. Creating a tuple is faster than creating a list. Creating a list is slower because two memory blocks need to be accessed. An element in a tuple cannot be removed or replaced.
What are differences between lists and dictionary?
A list is an ordered sequence of objects, whereas dictionaries are unordered sets. However, the main difference is that items in dictionaries are accessed via keys and not via their position. Any key of the dictionary is associated (or mapped) to a value. The values of a dictionary can be any type of Python data.
Which is faster dictionary or list?
So, dictionary is faster because you used a better algorithm. The reason is because a dictionary is a lookup, while a list is an iteration. Dictionary uses a hash lookup, while your list requires walking through the list until it finds the result from beginning to the result each time.
When would you use a list vs dictionary?
It is more efficient to use a dictionary for lookup of elements because it takes less time to traverse in the dictionary than a list. For example, let’s consider a data set with 5000000 elements in a machine learning model that relies on the speed of retrieval of data.
When would you use a list and dictionary?
12 Answers. A list keeps order, dict and set don’t: when you care about order, therefore, you must use list (if your choice of containers is limited to these three, of course ? ). dict associates each key with a value, while list and set just contain values: very different use cases, obviously.
