Splitting list into smaller lists of equal values

Question

I am looking to transform a list into smaller lists of equal values. An example I have is:

[\"a\", \"a\", \"a\", \"b\", \"b\", \"c\", \"c\", \"c\", \"c\"] 
<         


        

Answer 1

Another manner to have your desired output is by using defaultdict from collections module (best time using this approach was: ~= 0.02s same as using groupby):

from collections import defaultdict
a = ["a", "a", "a", "b", "b", "c", "c", "c", "c"]
b = defaultdict(list)
for k in a:
    b[k].append(k)

>>> b 
defaultdict(list,
            {'a': ['a', 'a', 'a'], 'b': ['b', 'b'], 'c': ['c', 'c', 'c', 'c']})

So, what you have to do now is:

list(b.values())
>>> [['a', 'a', 'a'], ['b', 'b'], ['c', 'c', 'c', 'c']]
