My understanding is that in your case

./index.pyhtml

is expanded to:
    
./preprocessor.py index.pyhtml

Notice the missing redirection "<". Your program however ignores the
command line argument and instead tries to read from stdin. Since this
is still the keyboard, it waits for you to type something.

Try to parse command line arguments and open the file to read using
open and a distinct file object. 

(If you insist on reading stdin, then sys.stdin=open(sys.argv[1],"r") 
after some error checking should do the trick).
