focal/python3-netaddr : SyntaxWarning: "is not" with a literal

[Harry Coin]

Setting up python3-netaddr (0.7.19-3) ...
/usr/lib/python3/dist-packages/netaddr/strategy/__init__.py:189: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  if word_sep is not '':

'is' and == are not the same, tests will fail that succeeded on some x86 cpython platforms for other than 8 bit literals.
These bugs are picked up on python3.8, included with focal, not seen on 3.7/eoan.

While dropping python-netaddr may remove a 2.0 issue, notice the bug
report was for python3-netaddr.  The 3 bit is important and doesn't fix
this bug.

Can we reopen this bug for focal?

It still happens with python3-netaddr.
