In this tutorial, you'll learn the key characteristics of lists and tuples in Python, as well as how to define and manipulate them. When you're finished, you'll have a good feel for when to use a tuple vs a list in a Python program.
Finally, let us list down all thedifferences between lists and tuples in Python, discussed above. List are created with square brackets and tuples are created with round bracket. Lists are mutable whereas Tuples are immutable. Tuples offer a little more memory efficient solution. ...
Internally, both lists and tuples are implemented as a list of pointers to the Python objects (items). When you remove an item from a list, the reference to an item gets destroyed. Keep in mind, that removed item can stay alive if there are other references in your program to it. ...
We store multiple values using list and tuple data structures in Python. We use the indices to state the position or location of that stored value. In Python, index values start from 0 untilthe length of tuple -1.For example, in the image above, we had a tuple containing three values (...
In Pyhton, a tuple is similar to list except it is immutable and are written with optional round brackets. Python tuples are faster during iteration.

We defined a tuple namedtuple_namesand a list namedlist_names. In the tuple definition, we used parenthesis()while in the list definition, we used square brackets[]. Python'stype()method helps easily identify the type of an object:
Lists in Python are dynamic arrays, meaning they require additional memory to store references to objects and accommodate potential resizing. Each element in a list has a reference pointer that points to the actual data, resulting in extra memory overhead. ...
Above, I re-declared the variable “hostnames” with a new tuple. This is no problem in Python so the “write protect” analogy doesn’t make much sense. Tuple vs List Why would you want to use a tuple instead of a list? To be honest, for us network engineers it doesn’t matter...
TypeError:unhashable type: 'list' >>>d[tuple(nums)]="hello" >>>d {(1, 2, 3): 'hello'} Another conflict between the Technical and the Cultural: there are places in Python itself where a tuple is used when a list makes more sense. When you define a function with *args, args is...
