Please Help...

Does anyone have a Python Script file to "Batch Import .e00 Files (w/in Directory/Sub-Directory) python script" for ArcGIS for Desktop 10.2, or can some one help me edit the importe00.py script which is included w/ ArcGIS for Desktop 10.2 (Code listed Below)?

I am attempting to create a .py file that will ask the user to select a "input directory" for the .e00 files, that will also search all sub-directories; then ask the user to select an "output directory" for the Coverage files.

I'm am extremely new to Python Scripting and really need help...

ESRI's importe00.py:


'''---------------------------------------------------------------------------
Tool Name:     ImportFromE00
Source Name:   importe00.py
Version:       ArcGIS 10.0
Author:        Environmental Systems Research Institute Inc.
Required Argumuments:  An input interchange file (.e00)
                        An output directory (where to put the output)
                        An output name (what to call the output)
Description:   Imports the contents of an ArcInfo interchange file
Notes:
- This script wraps ARCGISHOME/bin/import71.exe
- The executable only works on Windows with Desktop.

Thank you in advance.
