I need help

Question

I don't know why this code didn't work
I have error in test case4
s=input()
a=s.lower()
b=a.split()
lst=[]
a1=ord('a')
alfa=[chr(i)for i in range(a1,a1+26)]
for letter in a:
if letter in alfa:
lst.append(letter)
avrg=len(lst)/len(b)
if avrg==int(avrg):
avrg=int(round(avrg))
print(avrg)
else :
avrg=int(round(avrg)+1)
print(avrg)

Answer 1

Btw you can check if its an alphabetical letter with isalpha()
You dont need the alfa list

Answer 2

What is the purpose of your code and what are test cases?

Answer 3

What is the input? Is it a list of words or a sentence?
Or just tell me the name of the challenge than i can see the task by myself

Answer 4

import math

s = input().split()
count=0

for word in s:
count += len(''.join(i for i in word if i.isalpha()))

print(math.ceil(count/len(s)))

Answer 5

I would have done it this way for example

Answer 6

1. You dont need to make it to lower case and then check for the ord number cause yoi can just use isalpha() as i said before
2.you can also just count the letters and not append it to a list and after that use the length
3.you dont need to care about it the value is already a whole number and not a floating number if you use math.ceil cause this method always rounds up

Answer 7

It work thank you jnn

Answer 8

This is a challenge I want to get the average length of the words

Answer 9

Challenge name is average length of words and the input is sentence
