Question

def average_word_length(string):

num_words = 0

if not type(string)==str:

return "Not a string"

if not "A" or not "B" or not "C" or not "D" or not "E" or not "F" or not "G" or not "H" or not "I" or not "J"\ or not "K" or not "L" or not "M" or not "N" or not "O" or not "P" or not "Q" or not "R" or not "S" or not "T"\ or not "U" or not "V" or not "W" or not "X" or not "Y" or not "Z" or not "a" or not "b" or not "c" or not "d"\ or not "e" or not "f" or not "g" or not "h" or not "i" or not "j" or not "k" or not "l" or not "m" or not "n"\ or not "o" or not "p" or not "q" or not "r" or not "s" or not "t" or not "u" or not "v" or not "w" or not "x"\ or not "y" or not "z" in string :

return "No words"

else:

for i in string:

if i == " " and (i+1) == " ":

num_words += 0

if i == " ": num_words += 1

if i == "," or i == "." or i == "!" or i == "?":

num_words+=0

else:

num_words=1

if i == " ":

numl=len(string)-string.count(char)

if i=="," or i=="." or i=="!" or i=="?":

numl=len(string)-1

else: numl=len(string)

return numl/num_words

print(average_word_length("Hi"))
print(average_word_length("Hi, Lucy"))
print(average_word_length(" What big spaces you have!"))
print(average_word_length(True))
print(average_word_length("?!?!?! ... !"))

When the function works, the following code should output: 2.0, 3.0, 4.0, "Not a string","No words"

Not sure what the mistake is because it output something else

def average_word_length(string):
if not type(string)==str:
return "Not a string"

num_words = 0
word = ''
total_length = 0

for c in string:
if c in " \t\n,.!?": #check if its any delimiter character
if not word == '':
num_words += 1
total_length += len(word)
word = ''
else:
word += c

#increment for last word
if not word == '':
num_words += 1
total_length += len(word)

if num_words == 0:
return "No words"
else:
return total_length/num_words

print(average_word_length("Hi"))
