1 Introduction to Cognitive Science Final assignment Section 1: Python programming This section of the assignment asks you to answer some questions that primarily relate to Python programming, although they may also draw on your knowledge of other aspects of the course. This section of the final assignment is worth 12% of your grade for this course. The deadline for submitting this assignment is noon Thursday 17 December. Ensure that you read the linked web pages on ‘General Assessment Information’, including details on late penalties and late submission. That information can be found directly at: http://students.ppls.ed.ac.uk Instructions: • Answer BOTH questions below (Question 1 + Question 2) • Answer the questions neatly and clearly inside a single MS Word document. Ensure that the examiner can easily identify which question you answering and what your answer is. • Upload that the completed document to TurnItIn before the deadline Make sure to: • Include your exam number at the top (but not your name or student number) • Use a font size that is easily legible (precisely what size that is will depend on the font used, but for most fonts that will be at least 11 point) • Leave wide right and left margins (at least 2.5cm) • Use at least 1.5 line spacing • Number your pages consecutively Uploading to TurnItIn: • Go to Learn -> Assessment -> Assessment Submission • You will find a TurnItIn submission box for ‘Final assignment - Python section’ that will allow you to upload your completed document • Give your exam number (not your name or student number) as both the TurnItIn title and filename the file you submit (e.g. the file you submit should look something like ‘B34234.docx’) • Ensure you complete the associated ‘own work’ declaration alongside the submission box on Learn. It is essential that you complete this declaration. Please do not attempt to submit your answer in the form of a Python notebook. Questions? Please ask them on MS Teams ‘Python Chat’ channel! 2 QUESTION 1 The program below uses recursion to print a very long sentence clause by clause. The output is shown as well. def fun(c, x): if len(c)==1: return '\t'*x + c[0] else: return('\t'*x + c[0] + ' that \n' + fun(c[1:],x+1)) print(fun(['Martin said', 'Neil heard', 'Patrick believed', 'Mark thought', 'Jia explained', 'Hannah was late'], 0)) OUTPUT: Martin said that Neil heard that Patrick believed that Mark thought that Jia explained that Hannah was late (a) Rewrite the program with two additions to improve readability: (i) user-friendly comments and (ii) clearer variable/function names. You will leave the Python functionality the same (no changes to the Python structure or commands), but the new version you write with comments and new names will be easier to read. (b) Briefly relate recursion to the flexibility and productivity of natural language. Are infinitely long sentences possible and how does their (hypothetical) use inform debates about Nativism and Empiricism? 3 QUESTION 2 (a) There are three functions below. Consider each function and write out what it will output. Compare the output of the three functions: Do their outputs differ, and if so how? def function1(): word2 = "hello" word1 = word2 for i in range(3): print(i+1, word1) def function2(): word1 = "" word2 = "hello" for i in word2: word1 = word1 + i for n in range(4): print("{0} {1}".format(n, word1)) def function3(): word1 = "" word2 = "hello" for i in [1,2,3,4]: for n in word2: word1 = word1 + n print(i, word1) (b) Find the error(s) in the following Python code Numr = 4 second = numr+5 print(second) print(numr) (c) Find the error(s) in the following Python code x = range(10): for i in x: if x = 5: print “here’s the number 5!”
