in Scheme ### all-unique Function in SchemeThis task involves writing a function named `all-unique` in the Scheme programming language. The function should accept a list as input and return `true` if each element in the list appears only once. If any element appears more than once, it should return `false`. It is assumed that the list is flat, meaning it contains no nested lists.**Hint:** It might be helpful to implement a helper function called `contains` that checks if a list contains a specific item.#### Examples:- `(all-unique '(a b c 1 2))` should return `true`.- `(all-unique '(a b c 1 a))` should return `false`.- `(all-unique '())` should return `true`. This function can be useful for validating data sets where uniqueness is required, such as in ensuring no repeated values in a configuration or options list.

Step 1

The following problem is coded in Python programming language. As required, write a function all_unique which returns True if all the values in the list are unique, and False if all the values are not unique.

Technically speaking, Python is a high-level, object-oriented, dynamically integrated programming language that is largely used for the creation of websites and mobile applications. Since it provides possibilities for dynamic typing and dynamic binding, it is quite appealing in the realm of rapid application development.
