Question

I have some text manipulation to do, here’s a for loop that does it:

 for p in paras[:]:

     pidx = paras.index(p)

     for sent in p:
         sidx = p.index(sent)

         sent = ' '.join(w[0] for w in sent)
         paras[pidx][sidx] = sent

     paras[pidx] =  'start' + ' '.join(paras[pidx]) + 'end'

Here is my list comprehension:

 [' '.join(w[0] for w in sent) for p in paras for sent in p]

This returns one large list of sentences and I need separate lists based on the paragraph (p) or have some way to signify where the end of each para is. Is there some sexy way to do this?

Answer 1

A nested LC

[[' '.join(w[0] for w in sent) for sent in p] for p in paras]

should give each para as a separate list
