    PEP8 failed when import i18n more than one

    1. What is the problem
      When "from tricircle.common.i18n import _, _LE, _LI, _LW"
      The pep8 failed: ./tricircle/network/central_plugin.py:50:36:
      H301 one import per line

    2. What is the solution to the problem
      i18n import in one line is a valid exception, and could be skipped
      in pep8 test

    3. What the features need to be implemented to the Tricircle
      N/A
