Chapter2 Listing 2.3 returned [' ', ' ', ' ', ' ', ' ', ' ', ' ']

Hi. I tried the code in Chapter2 Listing 2.3, which is the following:

text = 'Define which data represents "ham" class and which data represents "spam" class for the machine-learning algorithm.'
text = "i. e."
delimiters = ['"', "."]
words = []
current_word = ""
for char in text:
if char==" ":
if not current_word=="":
words.append(current_word)
current_word = ""
elif char in delimiters:
if current_word=="":
words.append(char)
else:
words.append(current_word)
words.append(char)
current_word = ""
else:
current_word += char

print(words)

But it returned [' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ']. Would you happen to know why?
