How to list which feature layers are being used by which web maps and apps?

Question

Anybody got any tips or hints on how this can be done?

I've been able export lists of items by user and user folder using the following:
pd.DataFrame(list_items).transpose().to_excel(str(user.username)+'.xlsx')

But it would be more useful to see which web maps and web apps throughout my organization are using which feature layers.

I got the same error,

SyntaxError: invalid non-printable character U+200D

and found this:

https://www.decodingweb.dev/solved-syntaxerror-invalid-non-printable-character-in-python

I removed the non-printable characters using Notepad++ with this method from StackOverflow (https://stackoverflow.com/questions/20889996/how-do-i-remove-all-non-ascii-characters-with-regex-and-notepad)

'In Notepad++, if you go to menu Search → Find characters in range → Non-ASCII Characters (128-255) you can then step through the document to each non-ASCII character.

Be sure to tick off "Wrap around" if you want to loop in the document for all non-ASCII characters.'

After that, it worked like a charm!

Hi David, 
Have you figured out how to access the properties of a sublayer of a service?  For instance, I'm iterating through a map that has the entire service. When my script hits this layer, it does not iterate through the sublayer of the services. It simply prints the name of the main service.

Any insight would be greatly appreciated.
