Question 1 (already finished) Extract: "Data" From: "Introduction to Data Science" def question1(text): return (text[16:20], slice(16,20,1)) Notes and hints: 'extract' means return the substring that is to be 'extracted' (i. e. removed) from the 'From' text. if you want to debug your answers, just do the following (in main. py) import lesson as ans result = ans. question1("Introduction to Data Science") print(result[0] == 'Data') # looking for True you can also test each part of your expect = "Data" word = "Introduction to Data Science" s1 = slice(16,20,None) value = word[s1] if (value != expect): print("Bad Slice", expect, value) value = word[16:20] if (value != expect): print("Bad Index", expect, value) In each of your answers, you should ONLY use the slice function as part of the final return and you must use the parameter text in the return statement. do some answer(text): idx = some calculation() return (text[idx:20], slice(idx,20,1)) Bonus: ideally, you should solve each of these without any hardcoded numbers other than the step amount: Extract: "Data" From: "Introduction to Data Science" def question1(text): word = 'Data' wl = len(word) idx = text. find(word) return (text[idx:idx+wl], slice(idx, idx+wl, 1)) Question 2: Extract: "ar" From: "Orange" def question2(text): return (

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)
