1 01-18-24 (Thursday - Lab)

Dear Heavenly Father,
We start this day asking for your joy and strength in this moment when we are practicing these programming skills.
Please let this be a moment of true fellowship and character building in our community of learning.
Be with us in any difficulties we face. Give us a disposition to help, and humility to be helped.
Give us wisdom to discern your beauty and justice as we write these Python programs.
May everything we do and learn here be offered to you in praise, gratitude and service to our neighbors.
In Jesus name we pray. Amen.

2 Lab Instructions

  • Remember that lab attendance is required. If you cannot come, please let us know in advance. Not attending the lab without legitimate reasons will unfortunately receive 0 points.
  • Please don’t bring food and drink to this lab. (For classes in the other room, NH253, this is fine).

2.1 Pair programming

  • The basic idea:

    • Person 1 acts as a coder (typing into the code)
    • Person 2 acts as a code reviewer
    • Alternate the roles after each solving each problem
    • Both should discuss how to tackle the problem before coding

  • LOTS of advantages

    • Mutual learning
    • Helps spotting some stupid typos/mistakes we may end up writing (and these can difficult to detect later)
    • While one gives attention to the “tactical” aspect of getting some small stuff done, the other is thinking about the bigger picture, the “strategical” aspect.

  • It takes some patience to just sit and look at someone writing. We are not trained in this kind of attention. But in the end it can be VERY satisfactory.

  • In the end, submit just one copy per pair

    • Put down the names of both members as authors
    • Put down the class A/B
    • E.g., Frodo Baggins (Calvin-ID) A

2.2 Don’t forget headers in files

  • At the top of each program file, include something like this:
"""CS 108 - Lab 1.5
Use a simple formula to estimate pi which is
accurate to 6 digits.
@author: Frodo Baggins (123456) A
@author: Samwise Gamgee (654321) A
@date: Spring, 2024
"""
  • The template header is actually:
"""CS 108 - Lab/Homework X.X
Describe the module here. Fix the lab number above and
the name/date below.
Delete the second @author line if working solo.
@author: YOUR-NAME (yourid123) A/B
@author: PARTNER-NAME (theirid123) A/B
@date: semester, year
"""

2.3 Grading example for Lab 1

  • Each question carries 20 points
    • Test for documentation (2 points)
      • The file name checking (e.g., Lab1_1.py)
      • A brief description of the program file
      • Authorship (including the section)
    • Correctness (18 points for Lab1.1 and 16 points for others)
    • Code documentation (2 points)
      • i.e., concise and clear comments about the code
        • E.g., print(pi) # print out the estimated value of pi
