The main difference between a tuple and a list in Python is that tuples are immutable, while lists are mutable. This means that you can modify a list by adding, removing, or changing elements, but you cannot do

Syntax of list and tuple is slightly different. Lists are surrounded by square brackets[ ]and Tuples are surrounded by parenthesis( ). List=[1,2,3] Tuple=(1,2,3) 2. Mutable lists vs immutable tuples The main difference between lists and tuples is the fact that lists are mutable where...
Using the above methodology, we ultimately derive purely functional and imperative variants of reverse-mode AD: we successively improve the time complexity of scalar multiplication and gradient vector addition with representations based on homomorphisms, and switch to their equivalent mutable representation ...
Tuplesin Python is a collection of items similar to list with the difference that it is ordered and immutable. Example: tuple = ("python", "includehelp", 43, 54.23) Listis a sequence data type. It is mutable as its values in the list can be modified. It is a collection of ordered ...
