how to split two words into single word in a list in a easy way in python

Question

I have a list like this,

 my_list = ["one two","three two"]

I want to convert it to,

 out_list=["one","two","three","two"]

I am getting the output by doing,

out_list=[item.split() for item in my_list]
out_list=sum(out_list,[])

I am looking for the easiest way to do the same in a single line, but I hope there is a simple way to do this in python, Thanks in advance!

use the list flattening scheme `[x for y in my_list for x in y]` — Ma0, Jan 05 '18 at 09:29
an alternative `list(chain.from_iterable(map(str.split,my_list)))` — Chris_Rands, Jan 05 '18 at 09:30
@Ev.Kounis I am getting the characters one by one for your solution, my actual list has more items not 2 — Pyd, Jan 05 '18 at 09:46
Then your actual input and the one you used for the question are two different things, conceptually speaking. Post a more accurate example of your situation. — Ma0, Jan 05 '18 at 09:47
no, your `[x for y in my_list for x in y]` is not working for my above question too, please check in notebook — Pyd, Jan 05 '18 at 09:55
@pyd: I'm afraid you cannot since there are accepted & upvoted answers. But don't worry, you're not at fault here. — Jean-François Fabre, Jan 05 '18 at 10:42

A fun alternative to the obvious and superior in its generality answer by @Yarmash:

my_list = ["one two","three two"]
res = ' '.join(my_list).split()
print(res)  # -> ['one', 'two', 'three', 'two']

' '.join(my_list) creates a string that looks like this "one two three two" which is then split using the default delimiter (whitespace).

You can do it with a single list comprehension:

>>> my_list = ["one two", "three two"]
>>> [y for x in my_list for y in x.split()]
['one', 'two', 'three', 'two']
