Only a novice at Python. Using ArcMap for Desktop 10.3. My ultimate objective is to send some shapefiles to a zip file using script. I ran the above based on someone's existing script.

1.) What is if __name__ == '__main__': doing in this scenario?

      From what I understand you can use this when importing another Python script? That's why I have the       "RemoveAddLayer" script as an import at the top. I may be completely wrong?

2.) The RemoveAddLayer script (that's imported at the top) is what I created to update Streets and Address Points layers. Should I save these to a folder in the script and then set that as the path variable in the ZipFiles2 script?

There was no error when I ran this but also no file was put into the outpath folder. 

Edit: @Rebecca: Thanks, I took your advice and put the script in instead of the image.

I'll probably not get this 100% technically correct, but here goes:

Each script is blessed with a '__name__'. If the script is the main executing file, it gets the name '__main__'. You can also import any .py file as a module, like you did with RemoveAddLayer. When the code executes within RemoveAddLayer, I assume __name__ = 'RemoveAddLayer', or something similar, but definitely not '__main__'.

On the flipside, if you ran a different script that imported the script you've posted above, __name__ != __main__, so that part wouldn't execute. You would still have access to the ZipShapes() function in the first script, though. Clear as mud?

edit: there is lots and lots written out there. Search for '__main__' or '__name__'.
