Function Transformations Practice

In Doc2Doc, users are asking for a filtering feature. They want a command that has dynamic options so that they can work as quickly as possible.

Assignment

Complete the get_filter_cmd function. It takes two functions as input, filter_one and filter_two, and returns a function, filter_cmd.

filter_cmd should take as input two strings: content and option.

Set the default value of the option argument to --one.
Complete filter_cmd so that it filters and returns the content according to the input option.
1. If --one, use filter_one
2. If --two, use filter_two
3. If --three, use filter_one first, then use filter_two
4. If another option is passed, raise an exception, "invalid option"
