Strings are immutable sequences of Unicode code points from "summary" of Fluent Python by Luciano Ramalho
In Python, strings are immutable sequences of Unicode code points. Being immutable means that once a string object is created, its contents cannot be changed. If you try to modify a string, you'll end up creating a new string object. This might seem inefficient, but it has practical advantages in terms of predictable behavior and optimization opportunities. The fact that strings are sequences means that you can access individual characters or slices of a string using the indexing syntax. This makes strings similar to lists, but with some key differences. For example, you can't modify a string in place like you can with a list. This means that methods like `append` and `pop` that modify a list in place are not available for strings. The use of U...
