--description--

Given a password string, return "weak", "medium", or "strong" based on the strength of the password.

A password is evaluated according to the following rules:

• It is at least 8 characters long.
• It contains both uppercase and lowercase letters.
• It contains at least one number.
• It contains at least one special character from this set: !, @, #, $, %, ^, &, or *.

Return "weak" if the password meets fewer than two of the rules. Return "medium" if the password meets 2 or 3 of the rules. Return "strong" if the password meets all 4 rules.

--hints--

check_strength("123456") should return "weak".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("123456"), "weak")`)
}})

check_strength("pass!!!") should return "weak".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("pass!!!"), "weak")`)
}})

check_strength("Qwerty") should return "weak".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("Qwerty"), "weak")`)
}})

check_strength("PASSWORD") should return "weak".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("PASSWORD"), "weak")`)
}})

check_strength("PASSWORD!") should return "medium".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("PASSWORD!"), "medium")`)
}})

check_strength("PassWord%^!") should return "medium".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("PassWord%^!"), "medium")`)
}})

check_strength("qwerty12345") should return "medium".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("qwerty12345"), "medium")`)
}})

check_strength("S3cur3P@ssw0rd") should return "strong".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("S3cur3P@ssw0rd"), "strong")`)
}})

check_strength("C0d3&Fun!") should return "strong".

({test: () => { runPython(`
from unittest import TestCase
TestCase().assertEqual(check_strength("C0d3&Fun!"), "strong")`)
}})
