4. In a Coding Kwoon
Axioms:
People have different skill levels
There’re several ways to express ideas about what you’re trying to
accomplish
You can:
Exercise a set of skills
Learn with others and share what you know
Learn new languages
Explore details of languages you already know

6. Programming Challenge
Create an string representation of an integer value using a 3x3 grid and the
characters “.”, “_”, “|” to compose each digit.
All digits:
._. ... ._. ._. ... ._. ._. ._. ._. ._.
|.| ..| ._| ._| |_| |_. |_. ..| |_| |_|
|_| ..| |_. ._| ..| ._| |_| ..| |_| ..|
Example:
Input = 910
Output = ._. ... ._.
|_| ..| |.|
..| ..| |_|

7. First Test Case
Think about the most appropriate data structure, but don’t overthink
Don’t be afraid to change the representation once you find something
better
class SingleDigitTests(unittest.TestCase):
def test_zero(self):
display = SegmentDisplay()
self.assertEqual(display.show(0), [["._."],
["|.|"],
["|_|"]])

8. Warnings
No competition.
Focus on the process, not on solving the programming challenge.
Things to practice:
Pairing
TDD
Baby steps
Communication
