Here's some example code for you to reference as you work through the assignment:

from collections.abc import Callable


def multiply(x: int, y: int) -> int:
    return x * y


def add(x: int, y: int) -> int:
    return x + y


def self_math(math_func: Callable[[int, int], int]) -> Callable[[int], int]:
    def inner_func(x: int) -> int:
        return math_func(x, x)

    return inner_func


square_func: Callable[[int], int] = self_math(multiply)
double_func: Callable[[int], int] = self_math(add)

print(square_func(5))
# prints 25

print(double_func(5))
# prints 10

Assignment

Complete the doc_format_checker_and_converter function. It takes a conversion_function and a list of valid_formats as parameters. It should return a new function that takes two parameters of its own:

filename: The name of the file to be converted
content: The content (body text) of the file to be converted

If the file extension of the filename is in the valid_formats list, then return the result of calling the conversion_function on the content.
Otherwise, raise a ValueError with the following message:
```
invalid file format
```

Tips

You can use the .split() method on the filename to get the file extension. Then use the in keyword to check if a value is in a list.
capitalize_content and reverse_content are "conversion functions" that will be passed into our doc_format_checker_and_converter function by the tests.
