In this thread I received some assistance with getting this script to work correctly. The script essentially sets my network location according to the SSID I'm connected to. This is now working, however, it generates a lot of nuisance notifications.

Every time my laptop joins a wifi network, the script runs, sets the network location, and gives me a notification. Since power nap periodically joins the wifi to check for emails/updates and what have you, after a long weekend I'll get dozens of identical notifications.

How can I modify the script so that it only send a notification if the network location is changed to something different, not just when the script runs? Can I somehow check the existing network location and only change it/trigger a notification if the "new" location is different to the "existing" location?

Again, I'm extremely new to scripting on mac and GitHub in general; my previous experience is all on Windows and largely self taught.

Script:

I want to select words only if the word in each rows of my column not in stop words and not in string punctuation.

This is my data after tokenizing and removing the stopwords, i also want to remove the punctuation at the same time i remove the stopwords. See in number two after usf there's comma. I think of if word not in (stopwords,string.punctuation) since it would be not in stopwords and not in string.punctuation i see it from here but it resulting in fails to remove stopwords and the punctuation. How to fix this?
