❓ How to apply a map to all subsets ?

[astariul]

I'm working with CNN/DM dataset, where I have 3 subsets : train, test, validation.

Should I apply my map function on the subsets one by one ?

import nlp

cnn_dm = nlp.load_dataset('cnn_dailymail')
for corpus in ['train', 'test', 'validation']:
         cnn_dm[corpus] = cnn_dm[corpus].map(my_func)

Or is there a better way to do this ?

That's the way!
