Subject: Update slice.rst
X-Git-Url: http://git.silmor.de/gitweb/?a=commitdiff_plain;h=3ddff676f8f6484dc9e922ca36345940e2834606;p=web%2Fkonrad%2Ftwig.git

Update slice.rst

I was (somehow) misled by the example, thinking `'1234'[2:]` outputs `34` because it `2:` mean copy the last 2 characters...

This happens when you are in a hurry and didn't look into the text.

Let makes it less ambiguous.

 `substr`_ for strings.
