Question

Let’s say I have a list named

mylist = []

This list contains sentences from a file. My question is:

1. Is there a way I can add each element of mylist into separate sets?

2. If it can be done, then how to add to different set?

My code:

mylist = []
wordlist = open('data.txt', 'r').read().split()
ngrams = [wordlist[i:i+5] for i in range(len(wordlist)-4)]
mylist.append(ngrams)

print mylist

Some edits:

My output looks like this

[('hello', 'there')]
[("I'm", 'using'), ('using', 'python'), ('python', 'for'), ('for', 'the'),     ('the', 'first'), ('first', 'time.')]

What I want to do is add each of the bigram into separate sets.

Answer 1

I might be just misunderstanding your question, yet… are you trying any of these two?

Creating new sets from bigrams:

>>> li = [("I'm", 'using'), ('using', 'python')]
>>> [set(el) for el in li]
[set(['using', "I'm"]), set(['python', 'using'])]

Adding bigrams to existing sets:

>>> sets = [set([1]), set([2])]
>>> sets
[set([1]), set([2])]
>>> [sets[i].add(set_) for i, set_ in enumerate(li)]  #could be expanded in proper loop
[None, None]
>>> sets
[set([1, ("I'm", 'using')]), set([2, ('using', 'python')])]
