How to count value after a textblob

[LoliMarth]

Hello there,

I made a textblob with this piece of code : info = dataextract['Produit'] .apply(lambda x: TextBlob(x).ngrams(3))

My variable Produit -> https://image.noelshack.com/fichiers/201...apture.png There are more row of course.

I obtained this : https://image.noelshack.com/fichiers/201...pture1.png

I want to count all the occurence of my values in this list but all I get is 'TypeError: unhashable type: 'list''

So I tried this : tf1 = infoframe.apply(lambda x: pd.value_counts(x))

And I obtained this : https://image.noelshack.com/fichiers/201...pture2.png

But that's not exactly what I wanted, I want all the occurence for each term in []
Like all the occurence for [Samsung, Galaxy, S8]

I don't know if I'm clear but if you have any idea, don't hesitate to tell me about.

Thanks :)
