I reckoned the approach with the flag the most beginner-friendly because you
don't have to think too hard about the corner-cases, namely
>>> book_title("")
''
When I use the "process first item before the loop" approach I usually end
up with a helper generator
def _words(words, small_words={w.title(): w for w in small_words}):
yield next(words)
for word in words:
yield small_words[word] if word in small_words else word
def book_title(s):
return " ".join(_words(iter(s.title().split())))
and the nagging thought that I'm making it more complex than need be.
