B is a consonant

Approach

  1. A consonant is a letter (isalpha()) that is not a vowel.

Solution

Python
for ch in ["B", "e", "7"]:    if ch.isalpha() and ch.lower() not in "aeiou":        print(ch, "is a consonant")    else:        print(ch, "is not a consonant")
Output
B is a consonant
e is not a consonant
7 is not a consonant
