Both of these states are integral to Python data structure. If you want to become more knowledgeable in the entire Python Data Structure, take thisfree course which covers multiple data structures in Pythonincluding tuple data structure which is immutable. You will also receive a certificate on co...

A bytes object is a sequence of bytes, which are integer values ranging from 0 to 255. They are used to represent raw binary data or as a way to handle encoded text. Bytes objects are immutable and are created using the bytes() constructor or the b prefix before the quotes. bytes_exam...
Properties of Python Sets: Unordered in manner Immutable(you can't change then according your need) Sets are unindexed(you can get them by index number) Duplicasy is not allowed means you can't write same value more than one time.
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) Checking if the element is present in tuple In this article, we are given a tuple and an element. Our task is to crea...

Even integer n other primitives also immutable. But we don't consider it in reality. Then y to strings, when we are getting required (reassigned) values? Why to consider the string pools also when coding? I need an example to understand this. If it is understood, have an...
