I think you do it with a generator like this:
def flatten(nested): for sublist in nested: for element in sublist: yield element
n=[['N', 'F'], ['E'], ['D']] output=[]
for value in flatten(n): output.append(value)
print output
I highly recommend learning about the stdlib module "itertools" (I only really looked into it recently). The above can be done in 3 lines (counting imports):
from itertools import chain n = [['N', 'F'], ['E'], ['D']] print [chain(*n)]
