Why would you write some C-program just to save having two separate
files, one batch and one for the script?  For that matter, several
answers have given you approaches that didn't involve list
comprehensions, including merging the two in a single file, using an
initial variable of rem=""" 

What are your real constraints?  Are you just playing code-golf?
