--description--

Given a string and a target number, determine whether the string contains exactly the target number of consonants.

  • Consonants are all alphabetic characters except "a", "e", "i", "o", and "u" in any case.
  • Ignore digits, punctuation, spaces, and other non-letter characters when counting.

--hints--

has_consonant_count("helloworld", 7) should return True.

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(has_consonant_count("helloworld", 7), True)`)
}})

has_consonant_count("eieio", 5) should return False.

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(has_consonant_count("eieio", 5), False)`)
}})

has_consonant_count("freeCodeCamp Rocks!", 11) should return True.

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(has_consonant_count("freeCodeCamp Rocks!", 11), True)`)
}})

has_consonant_count("Th3 Qu!ck Br0wn F0x Jump5 0ver Th3 L@zy D0g.", 24) should return False.

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(has_consonant_count("Th3 Qu!ck Br0wn F0x Jump5 0ver Th3 L@zy D0g.", 24), False)`)
}})

has_consonant_count("Th3 Qu!ck Br0wn F0x Jump5 0ver Th3 L@zy D0g.", 23) should return True.

js
({test: () => { runPython(`
from unittest import TestCase
TestCase().assertIs(has_consonant_count("Th3 Qu!ck Br0wn F0x Jump5 0ver Th3 L@zy D0g.", 23), True)`)
}})
