First thing: Don;t use IODLE as your interpreter. IDLE is a
development environment that should not be used for running
code in "production" type environments. Python is the interoreter,
use it directly.

If the script take a filename as an input parameter you can likely do

python myfile.py *.*

from the OS command prompt.

Or in MacOS or Windows select all the files in Explorer and drag them 
onto
your script. I suspect most Linux desktops will allow the same.

Or you could write a second python script that traverses the files in 
your
folder and calls a function which contains your code (recall that a 
python
file can be impoerted as a module into another python file...)

Just some ideas,
