How do I turn a list of lists of words into a sentence string?

Question

I have this list

[[\'obytay\'], [\'ikeslay\'], [\'ishay\'], [\'artway\']]

where I need it to look like

obytay ikeslay ishay ar         


        

Answer 1

It is a list of strings. So, you need to chain the list of strings, with chain.from_iterable like this

from itertools import chain
print " ".join(chain.from_iterable(strings))
# obytay ikeslay ishay artway

It will be efficient if we first convert the chained iterable to a list, like this

print " ".join(list(chain.from_iterable(strings)))
