Tuples are immutable and hence cannot have any changes in them once they are created in Python. This is because they support the same sequence operations as strings. We all know that strings are immutable. The index operator will select an element from a tuple just like in a string. Hence...
With this, we have given you a refresher on what are arrays in Python and their usage. You may also be interested in finding the array length. Here, length refers to how many elements are present in the Python array. You can use the len() function to determine the length. It is as ...
