Are Python Strings Mutable?

No, Python strings are immutable, meaning that once a string has been created, its contents cannot be changed. This property of strings makes them efficient for various string processing tasks and allows for optimized string operations.

For example, if you want to change a character in a string, you need to create a new string with the desired changes. For instance:

>>> s = "hello"

>>> s = s[:2] + "p" + s[3:]

>>> print(s)

"help"

If you need to make frequent updates to a string, it may be more efficient to use a list of characters instead. Lists are mutable in Python, and you can easily concatenate lists of characters into a single string when you're done processing the data.
