Issue creating Python script to batch convert .e00 files to shapefiles (.shp) with ArcGis 10.4.1

Question

Hi there. I'm not only new to Python, but also to ArcGis and I'm quite stuck trying to create a script to batch convert .e00 files to .shp files. I've started working with a script that I found in this very own site, but I'm not able to make it work properly. It seems that the first part of the code, where the conversion to coverage files is made, runs fine, but the second part, where the conversion to .shp files should be made, doesn't work. It just does anything. I don't get any traceback erros. Could you please give me a hint? import arcpy, os arcpy.env.overwriteOutput = True arcpy.env.workspace = ws = r'C:\in' out = r'C:\out' if not os.path.exists(out): os.makedirs(out) for cov in arcpy.ListFiles('.e00'): arcpy.ImportFromE00_conversion(cov, ws, cov.split('.')[0]) print 'Converted %s' %cov for cov in arcpy.ListFiles(): if not '.e00' in cov and cov != 'info': arcpy.env.workspace = os.path.join(ws,cov) for fc in arcpy.ListFeatureClasses('*polygon'): shp = os.path.join(out, '%s.shp' %cov) arcpy.FeatureClassToFeatureClass_conversion(fc, out) print 'Converted Coverage to %s' %shp‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Thank you so much in advance. conversion.py.zip

Sorry for the delay in replying to you.

I'm using Python 2.7.5 with  ArcGIS 10.4.1 for Desktop Advanced, Product Version: 10.4.1.5686.

I've tried to use ListDatasets instead of ListFiles without success. Since this is older code, I'm starting to think that it might be better to restart from scratch.

Thanks again for your help, I truly appreciate it.

If you're just starting with Python, there's really no reason to use anything but the correct indentation scheme -- 4 spaces. Making your code legible is just as important as including the complete error messages, or adding diagnostic arcpy.AddMessage() lines just inside each for loop to trace execution flow.

Thank you, Rebecca.

I'm not at the office right now, but as soon as I get there, I'll let you know what version of the software I'm exactly using.

Until then, I'll dig into the documentation to learn more.
