Python String Immutability
The string is unalterable means that you can not change the object itself, but you can change the reference to the object. When you execute a = "ty", you're changing the reference of a to a new object created by the String objective "ty".
How do you make a string unalterable in Python?
In Python, a string is unalterable. You can not overwrite the values of unalterable objects. Notwithstanding, you can assign the variable again. It's not modifying the string object; it's creating a new string object
 Mutable is when being is changeable or can change. In Python,‘ changeable is the capability of objects to change their values. These are hourly objects that store a collection of data.
Immutable
Immutable is when no change is possible over time. In Python, if the value of an object can not be changed over time, either it's known as unalterable. Once created, the value of these objects is undying.
Reasons for String Immutability
It's responsible for determining where to store strings. In the last section, I noted that a string is an array of characters. The CLR implements an array to store strings. Arrays are a fixed-size data structure, meaning that they can not be forcibly increased or lowered in size. Once an array is assigned a size, the size can not be changed. To make an array larger, the data must be copied and replicated into a new array, which is put into a new block of memory by the CLR. However, you're not modifying that string; rather, the CLR is creating a new memory reference for the modified string, If you edit a string.
