Git & GitHub Activities

In the breakout rooms, each person should individually complete following tasks. The goal is muddle your way through - git can be difficult. Let's practice in low stakes environment. When get stuck ask someone else in the breakout rooms to help you.

Learning Outcomes

By the end of this session, you should be able to:

Career Advice Heuristics

Time-travel - What opportunity would I be happy having completed 1 or 5 years from now?
Largest hill to succesful climb - Most careers are a series of increasing larger hills to climb. Thus, which opportunity allows me to finish the biggest project possible?

Problem Statement

A robot starts at position (0, 0). Given a sequence of its moves, judge if this robot makes a complete trip. A complete trip means the robot ends back at the original location.

The valid robot moves are "R" (Right), "L" (Left), "U" (Up) and "D" (down). For example, a sequence of moves could be "RRLUUD". The robot would move:

Move 1 unit to the right
Move another 1 unit to the right
Move 1 unit to the left

Is Substring Problem

Problem Statement

Given a short string and long string, find if the shorter string is a substring of the longer string.

Common Questions

Data Science Workflow

Step 1 - Ask

Based on domain experience, ask specific and meaningful questions.

Define all terms precisely within the context.

Prompt:

It is the beginning of practicum, your industry mentor asks your practicum group to write an email to the entire the company introducing yourselves. For the sake of the activity, the organization is a hot, new start-up called Meow-Meet - Tinder for cat-lovers. Your practicum is on the Experimentation Team.

This is based on a real story. A couple of years ago, I was an industry mentor working with MSDS students. The students would not write this email. I had to ask several times and got really annoying. Let's practice now.

Steps:

Work together in Riseup Pad.
Write the subject line.

	"Make folders based items in a file."

	from pathlib import Path

	names = Path("names.txt").read_text().split("\n")

	for name in names:
	p = Path("/output/") / name
	p.mkdir(exist_ok=True)

	# Solution for Homeward Bound Robot Problem

	def test_is_back_at_start(is_back_at_start_func):
	# Complete trips
	assert is_back_at_start_func("UD") # Simple example
	assert is_back_at_start_func("ULDRLRDU") # A more complex example

	# Incomplete trips
	assert not is_back_at_start_func("LL") # Simple example
	assert not is_back_at_start_func("RRLUULRLRL") # A more complex

	# Solution for Is A Substring Problem

	def is_substring(short:str, long:str) -> bool:
	for i, c in enumerate(long):
	if c == short[0]:
	if long[i:i+len(short)] == short:
	return True
	else:
	return False
