unity-tweak-tool

Hello
it seems to me that the installation of unity-tweak-tool is going wrong

Paramétrage de unity-tweak-tool (0.0.7+-0ubuntu9) ...
/usr/lib/python3/dist-packages/UnityTweakTool/__init__.py:136: SyntaxWarning: "is not" with a literal. Did you mean "!="?
  assert id is not -1
/usr/lib/python3/dist-packages/UnityTweakTool/section/spaghetti/theme.py:155: SyntaxWarning: "is" with a literal. Did you mean "=="?
  self.ui['check_cursor_size'].set_active(True if gsettings.interface.get_int('cursor-size') is 48 else False)
