While it is possible to replace the loop with
next(filter(print, read_pdf("book.pdf")), None)
or the slightly less convoluted
sys.stdout.writelines(map("{}\n".format, read_pdf("book.pdf")))
the for loop is the obvious and therefore recommended solution. Personally,
I would also replace
> yield from (pg.extractText() for pg in pdf.pages)
with the good old
for pg in pdf.pages:
yield pg.extractText()
and reserve the generator expression for occasions where it has a
demonstrable advantage in readability.
