Create a Python class, Document. Using PYTHON: The instances of this class have the following attributes: word_count, status, grade, asked_grade_before_submission_count and the following methods: add_words, submit, get_grade, (1) key - a class attribute that determines the output when printing the document instance. It has a value of 0 by default. Let us also add these additional method/s for the Document class: str . For this exercise, we will add the following attribute/s: (1) copy_content - takes in source_document as a parameter of type Document then updates the word_count of the destination document (or the document where this method was invoked). The word_count is updated accordingly so that the content of the destination document is replaced by the source document. (2) append_content - takes in source_document as a parameter of type Document then updates the word_count of the destination document. The word_count is updated such that the content of the source document is appended to the destination document. Input Format The inputs are commands that can access an attribute or invoke a method of a Document instance. These commands can either be valid or invalid. Constraints String arguments when creating a Document instance and when invoking the add words method will be limited to 1000 characters at maximum. Only alphanumeric characters will be used as an argument to these methods. The invalid commands only include those that are trying to access an attribute of the object that is undefined. Format The output will be composed of 5 - 6 lines. The first five lines show the stats of the document being printed. The other is either an empty string or a string that shows one out of many descriptions of the Document instance being printed. Sample Input 2 essay = Document ("Roses are red") classes ['essay'] = essay essay_draft = Document ("Violets are blue") classes ['essay_draft'] = essay_draft essay. append_content(essay_draft) essay.add_words ("Sugar is sweet and so are you") essay.key_1 essay.delete( ) essay.key = 0 exit Sample Input 0 essay = Document ("Roses are red") classes ['essay'] = essay essay_draft = Document("Violets are blue") classes ['essay_draft'] = essay_draft essay.append_content(essay_draft) essay.key = 0 exit Sample Output 0 Valid command Valid command Valid command Valid command Valid command Sample Output 2 Valid command Valid command Valid command Valid command This Document instance has the following stats. 1. word count: 6 Valid command Valid command Valid command 2. status: draft 3. grade: awaiting submission 4. number of times the grade was requested before the document was submitted: 0 Invalid command Invalid command Valid command This Document instance has the following stats. 1. word count: 13 2. status: draft 3. grade: awaiting submission 4. number of times the grade was requested before the document was submitted: 0 Sample Input 1 essay = Document ("Roses are red") classes['essay'] = essay essay_draft = Document("Violets are blue") classes ['essay_draft'] = essay_draft essay.append_content (essay_draft) another_essay_v2 = Document ("Go away Anna!
