I can't return a value

I'm trying to write a function that will translate the input into so-called "cow Latin." I want to return the values from the if statement but whenever I do I get a syntax error. I can print the value but I want to avoid the function returning None as well. 

def cow_latinify_sentence(sentence):
    vowels = tuple('aeiou1234567890!@#$%^&*()-_=+|\\][}{?/.\',><`~"')
    sentence = sentence.lower()
    sentence_list = sentence.split()
    for i in range(len(sentence_list)):
        cow_word = sentence_list[i][:]
        if cow_word.startswith(vowels):
            print('{0}moo'.format(cow_word), end=' ')
        else:
            cow_word = sentence_list[i][1:] + sentence_list[i][:1]
            print('{0}oo'.format(cow_word), end=' ')

cow_latin = cow_latinify_sentence("the quick red fox")
print(cow_latin)

In short, how can I get the function to return instead of print?

    return result.strip()

You need to create a list to accumulate your results. 

result = []

your two print statements in your function would need changed to result.append(XXXX). Then when you have processed the entire sentence you can

return (result)

or, to re-form it into a sentence:

return " ".join(result) + '.'

    return result.strip()

>>> cow_latinify_sentence('hello there i am a fish')
'ellohoo heretoo imoo ammoo amoo ishfoo'

Why not just replace the two instances of

print('{0}moo'.format(cow_word), end=' ')

with 

return '{0}moo'.format(cow_word)+' '

You have to get rid of end=; you don't have to replace the newline that would otherwise follow the output of print, but if you want a space at the end of the returned string you still have to append it yourself.
