In this code, we are declaring type of parameters in function definition, also declaring type of output.

i just wanted to add some more information about type annotations. > just using type annotations in an editor like *sololearn playground* or other *basic editors* does not make sence, since python does not do anything actively with this information, it just *provides* the information. >> this is totally different with an editor like *visual studio code* (or other professional editors) by using the ide plugins like *pylance* or other linters. these tools /plugins are using the type annotations from the code file actively. > they show e.g. warnings when there is a type mismatch from a function call and the corresponding paramarer type. so when we type the function name with a pair of parenthesis, the required data types are shown in a popup window. > code areas that are affected by type problems will be underlined with a red *wavy* line. > so using type annotations in the discribed way makes a lof of sence for me, because it reduces errors in coding.

An annotation is only an annotation. It is rather part of the documentation. It does NOT do any type validation.

The answer is: Python is not the appropriate language for it. If you want this feature, use a language like Java which uses static typing. Anyways https://code.sololearn.com/c81BOyOW7CIu/?ref=app

But we can assign any type of variable (str, int, float etc.) . Unable to understand whole code. Can anyone explain this?
