Find the average length of all words in a sentence

Given a string consisting of words separated by spaces (one or more). Find the average length of all words. Average word length = total number of characters in words (excluding spaces) divided by the number of words. My attempt: But input is incorrect, can you help me?

sentence = input("sentence: ")
words = sentence.split()
total_number_of_characters = 0
number_of_words = 0

for word in words:
    total_number_of_characters += len(sentence)
    number_of_words += len(words)

average_word_length = total_number_of_characters / number_of_words
print(average_word_length)

Answer

When you’re stuck, one nice trick is to use very verbose variable names that match the task description as closely as possible, for example:

words = sentence.split()

total_number_of_characters = 0
number_of_words = 0

for word in words:
    total_number_of_characters += WHAT?
    number_of_words += WHAT?

average_word_length = total_number_of_characters / number_of_words

Can you do the rest?
