> Python 3 removed several deprecated functions / types.
>  
> {noformat}
> # sys.maxint is removed, replace with sys.maxsize
> sys.maxint -> sys.maxsize
> # file() is removed, use open()
> file() -> open()
> # Long is gone, int is now equivalent to long, can use int from future
> from builtins import int
> long() -> int()
> # e.message is gone, replace with str(e) 
> e.message -> str(e){noformat}
> There are a grab bag of others like strings.letters becoming string.ascii_letters and codecs moving to a different package.
> This is also a good time to get the new behavior for round().
> See these descriptions:
> [https://python-future.org/compatible_idioms.html#file]
> [https://python-future.org/compatible_idioms.html#long-integers]
> This corresponds to these pylint checks:
> file-builtin
> long-builtin
> invalid-str-codec
> round-builtin
> deprecated-string-function
> sys-max-int
> exception-message-attribute
>
