Study Notes
General Exam Information
- First year implementing Python in this class, differing from previous R course curriculum.
- Part I of the exam scheduled for 150 minutes with approximately 20 questions.

- No Part II for this year's exam.
Final Exam Overview
- Course: GBA 464: Programming for Analytics.
- Instructor: Yufeng Huang.
- Exam date: August 23, 2023.
- Total duration of exam: 2 hours and 55 minutes, split into two parts.
- Part I duration: 80 minutes, consisting of 14 questions worth 70 points.
- First six questions are multiple choice; subsequent eight involve coding or predicting output.

Question Highlights
- Question 1: Identifies built-in objects in Python; correct answer is Methods (D).
- Question 2: Assigning
x = "2012-02-28"results in a String (C). - Question 3: Fetching the output
-5from a list usingprint(a[3])is correct (B). - Question 4: A list containing only integers is
vec = [90, 30, -199, 9](C). - Question 5: Function output from
f(2)after considering variable scope, correct answer is 8 (A); variable scoping not covered in class, so students can skip this question. - Question 6: To convert DataFrame to wide format, the correct operation is
city_income.pivot(index='city', columns='gender', values='income')(A).
Suggestions for Preparation
- Focus on understanding Python objects, data types, lists, and functions.
- Familiarize with pandas DataFrame manipulation, including pivot operations.
- Review academic honesty policy to maintain integrity during the exam.
