5.6. Delete Answers from the Exam

Hasan is a teaching assistant at his university. He wrote exam questions for students, but right before he uploaded them into the website he realized that he forgot the answers of the questions in the text file. Can you help Hasan with writing a function that deletes answers from the question texts. Every 6th line in the text is the answer line.

Write a function named delete_answers which gets a string as a file name where the question and answers are recorded as strings. This function must write the questions without answers to a new file called new_questions.txt.
