Can someone tell me why i get None at the end please this has me stuck for ages

You get None b/c that's what's being returned from your join strings
function. Your function already prints out the result and doesn't
return the joined strings a your usage case expects.

So either return the joined strings from your function and don't print
them inside the function, or vice versa. Besides, can't you just use

print "".join(list_of_strings)

?
