如何在python中创建元音计数器

Question

Title says all! I am trying to make a " Display Stats" option in my menu i created. It would display the following after inputing a sentence. For example: String Analysis: 6 words 26 Characters 9 Vowels 17 Consonants. I made the whole word and character counter already now i need to do vowel and consonants, can someone help me please? Id highly appreciate the support!

What i got so far:

def displayst():
    print()
    print("You said the following:")
    time.sleep(1)
    length = str(input("Please enter your sentence: "))
    word = dis(length)
    lengths = diss(length)
    vowel = disv(length)
    print(length)
    time.sleep(1)
    print()
    print("String Analysis:",'\n', word, "Words",'\n', lengths, "Characters",'\n',vowel,"Vowels",'\n')
    again()

The vowel = disv(length) is what i need to finish and if you could help with consonants that would be great! If not i mainly need the vowels done as consonants i guess i could give it a try haha.

Then in my disv(length):

vowels = 'aeiou'
count = {}.fromkeys(vowels,0)
for char in length:
   if char in count:
        count[char] += 1
print(count)

Its all crazy and i honestly havnt a clue where im going with this haha. Please help cheers.

Answer 1

If you want a count, use a Counter dict:

from collections import Counter

inp = input("Please enter your sentence: ").lower()
cn = Counter(inp)
vowels = {v: cn[v] for v in "aeiou" if v in cn}
cons = {c: cn[c] for c in "bcdfghjklmnpqrstvwxyz" if c in cn}

if you want the total count just sum the values:

 print(sum(vowels.values()))

 print(sum(cons.values()))

If you just want the sums:

vowels = sum(cn[v] for v in "aeiou")
cons = sum(cn[c] for c in  "bcdfghjklmnpqrstvwxy")

Answer 2

You are not returning anything from disv that's why it is saying vowels None.You can use counter to get the vowel count

from collections import Counter

x = Counter(length)
vowel_count = 0
for v in "aeiou":
    vowel_count += x[v]
return vowel_count

This will return the exact number of vowels in your sentence.

Answer 3

def getInput():
    sentenceInput=input('Enter your sentence: ')
    return sentenceInput

def count(sentenceInput):
    vowelList=['a','e','i','o','u']
    vowelCount = 0
    constCount = 0
    spaceCount = 0
    for char in sentenceInput:
        if char in vowelList:
            vowelCount += 1
        elif char == ' ':
            spaceCount += 1
        else:
            constCount +=1
    print ('Length: ' + str(len(sentenceInput)) + ', Words: ' + str(spaceCount) + ', Vowels: ' + str(vowelCount) + ', Consonants: ' + str(constCount))

count(getInput())

Answer 4

vcount = sum([s.count(v) for v in 'aeiou'])

The list comprehension in side the [] returns a list of the occurrences of each vowel. The outer sum sums up the counts to give a total vowel count.
