This line is top-posted.  Please put your remarks *after* the part
you've quoted.

There isn't one slice, but many of them.  So you have a list of lists.

Each item in new is a list, since you created it with a slice.  So x is
a list, and when you print it, you get the default representation,
including the square brackets.  If you want to print the individual
items within x, separated by some marker of your choice, then you have
to write such code.

Instead of print x, you might want
       for item in x:
              print item,

This would show the items separated by a space.

Or you might want them separated by a comma:

     print ",".join(x)
