Help, pls. Average in words.

Question

I'm trying to solve the task "Average in words", but all the time i can't pass two last tests and I can't see why. In PyCharm my program works.
Here the task:
"You are in a college level English class, your professor wants you to write an essay, but you need to find out the average length of all the words you use. It is up to you to figure out how long each word is and to average it out."

Here is my decision:

from math import ceil

words = input()
letters = 0
words_temp = ''
words_lst = []

for i in words:
if i.isalpha() or i in '\'`': # for words like "I'm, you're, don't" and etc.
if i not in '\'`':
words_temp = words_temp + i
letters += 1
elif words_temp != '':
words_lst.append(words_temp)
words_temp = ''

print(ceil(letters / len(words_lst)))

Answer 1

I tested your code with "hello world".
output: 10

average should be 5.
each word has a length of 5. two words -> (5 + 5) / 2 = 5

Answer 2

Thank you :) I thought of everything except that there will be no any punctuation mark at the end of sentence :))

Maybe you get more answers if you remove "wtf" ;)

You are printing ceil(). This function does not return an integer, right?

Answer 4

Input Format:
A string containing multiple words.

Output Format:
A number representing the average length of each word, rounded up to the nearest whole number.

Sample Input:
this phrase has multiple words

Sample Output:
6

Answer 5

This function rounds the number to a larger integer and I pass 3 first tests
