#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

In JavaScript, string values are immutable, which means that they cannot be altered once created.

For example, the following code:

var myStr = “Bob”;

myStr[0] = “J”;

cannot change the value of myStr to Job, because the contents of myStr cannot be altered. Note that this does not mean that myStr cannot be changed, just that the individual characters of a string literal cannot be changed. The only way to change myStr would be to assign it with a new string, like this:

var myStr = “Bob”;
