Subject: remove use of Python 2 syntax in some demo files
X-Git-Tag: 2.48.0~9^2~13
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=84822dba6a7fb649669bb253489adf7dccf50652;p=graphviz

remove use of Python 2 syntax in some demo files

The last remnants of Python 2 support were removed in
61ae0419198465b457df875881a2dae0aadc8bfd. So it makes sense to update these
examples to be Python 3 only.
