1"Paper"
5"Wood"
10"Tin"
25"Silver"
40"Ruby"
50"Gold"
60"Diamond"
70"Platinum"
  • If they haven't reached the first milestone, return "Newlyweds".

get_milestone(0) should return "Newlyweds".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(0), "Newlyweds")`)
}})

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(1), "Paper")`)
}})

get_milestone(8) should return "Wood".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(8), "Wood")`)
}})

get_milestone(10) should return "Tin".

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(get_milestone(10), "Tin")`)
}})
