The output should display as follows...

PROGRAM: Vowel count

Please, enter a text string: fred
4 characters
a e i o u
0 1 0 0 0
b c d f g h j k l m n p q r s t v w x y z
0 0 1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 

It works; but, I believe is way over long...; maybe, I should have used arrays/or, ASCII count/-etc.?



print("PROGRAM: Vowel count\n")

aString=input("Please, enter a text string: ")

for eachChar in aString:

    if eachChar in vowels:
        if eachChar == "a": aCount+=1
        if eachChar == "e": eCount+=1
        if eachChar == "i": iCount+=1
        if eachChar == "o": oCount+=1
        if eachChar == "u": uCount+=1

    if eachChar in consonants:
        if eachChar == "b": bCount+=1
        if eachChar == "c": cCount+=1
        if eachChar == "d": dCount+=1
        if eachChar == "f": fCount+=1
        if eachChar == "g": gCount+=1        
        if eachChar == "h": hCount+=1
        if eachChar == "j": jCount+=1
        if eachChar == "k": kCount+=1
        if eachChar == "l": lCount+=1
        if eachChar == "m": mCount+=1
        if eachChar == "n": nCount+=1
        if eachChar == "p": pCount+=1
        if eachChar == "q": qCount+=1
        if eachChar == "r": rCount+=1
        if eachChar == "s": sCount+=1
        if eachChar == "t": tCount+=1
        if eachChar == "v": vCount+=1
        if eachChar == "w": wCount+=1
        if eachChar == "x": xCount+=1        
        if eachChar == "y": yCount+=1
        if eachChar == "z": zCount+=1



  • \$\begingroup\$ I've gone and corrected the sample output by changing 'upper case' F to become 'lower case' f. Thanks! ;-) \$\endgroup\$ Dec 4, 2018 at 23:39

To count the occurrences of things, use collections.Counter.

The lowercase letters are available as a predefined constant string.ascii_lowercase. You can use a generator expression to filter out the vowels and obtain the consonants. PEP 8, the official style guide, suggests using ALL_CAPS as names for constants.

I've used the * operator when calling print() to treat each element of a tuple or list as a separate argument.

Note that your formatting will break when any character has more than 9 occurrences.

from collections import Counter
from string import ascii_lowercase

VOWELS = tuple("aeiou")
CONSONANTS = tuple(c for c in ascii_lowercase if c not in VOWELS)

print("PROGRAM: Vowel count\n")
s = input("Please, enter a text string: ")
counts = Counter(s)

print('{0} characters'.format(len(s)))
print(*[counts[c] for c in VOWELS])
print(*[counts[c] for c in CONSONANTS])
