Program pdftk can merge pdf's, but I have never tried it.
You may also use pdflatex --- there is a package called pdfpages
provides powerful command \includepdf.

and also with the first example
getCompletedTime(start, end): return "Time completed:", str(end -

if you need to print just add print, if you want result from this
function somewhere else you got it. adding additional arguments
necessary adds complexity. do you really need it. Keep it simple stupid
