Question
Explain what’s going on below; is x mutable?x = 'abc'x = x.upper()
Solution
In the given code, we are dealing with a string in Python.
Step 1: x = 'abc'
Here, we are assigning the string 'abc' to the variable x.
Step 2: x = x.upper()
In this step, we are calling the upper() method on the string 'abc'. This method returns a copy of the original string, but with all the characters in uppercase. The result 'ABC' is then assigned back to the variable x.
As for the question "is x mutable?", the answer is no. In Python, strings are immutable, which means they cannot be changed after they are created. When we call x.upper(), it doesn't change the original string 'abc'. Instead, it creates a new string 'ABC' and assigns it to x. So, we are not changing the original string, but rather reassigning x to a new string.
