Yep, someone already answered that you can create the file in write mode 
and then close it, but I wanted to add a little more in why your 
solution doesn't work.

You're not interpolating the filename INTO the os.system string


The following would work

  for i in routers:
      os.system('/bin/touch %s'%1)

Granted, you should also provide a filename with a full path for simplicity.
