How to determine all python-nautilus extensions in use?

I need to provide an application developer with a list of all other python-nautilus extensions I have installed/running (I am trying to provide information on this issue).

What is the easiest way to get a list of these extensions on my machine?

(Please tag this with "python-nautilus")

Update 2021: On newer versions, such as 20.04, have a look into

/usr/lib/x86_64-linux-gnu/nautilus/extensions-3.0/

but this does not contain Python extensions, but in there is a file libnautilus-python.so.

According to this answer, you should also have a look in these directories in your home directory:

~/.local/share/nautilus-python/extensions/
~/.local/share/nautilus/scripts

Still found these directories on my v14.10, and on my v20.04.

User hhlp's answer already says that the system folders were (for older Ubuntu versions):

/usr/lib/nautilus/extensions-2.0/python 
/usr/lib/nautilus/extensions-3.0/python 

It seems to me that these no longer exist on my 20.04.

you can find them in two directory :

/usr/lib/nautilus/extensions-2.0/python 

/usr/lib/nautilus/extensions-3.0/python 

hope it help...
