Rewrite features that are no longer supported (or recommended)
in Python 3 in the script so that it can be used with both
Python 2 and 3, namely:
- print is not a statement; use print() function instead.
- dict.has_key(key) is no more; use "key in dict" instead.
- map(lambda ..., collection) is not liked; use list comprehension.
These changes introduce a syntaxe compatible with the both versions of
python.
Python 2 is EOL at the end of 2019, the major part of distros
and systems now come with python 3 is the default version so
these address the situation to render this script compatible with
the latest versions of python.
