Greetings! We appreciate the feedback. We really want that code map to be able to handle everything and so I consider it a bug that it fails for that--but I do think it's valuable that it fails since that led you to let us know it's broken. :) Fortunately, you can already get the behavior you're looking for. `wx_code_map` is a regular python dictionary, so you can us it's built-in `get` method: https://docs.python.org/3/library/stdtypes.html#dict.get like this: wxcode_num = wx_code_map.get(wxcodes.split()[0], 0) Hope this helps, Ryan > One last thing about MetPy . . . > > If a bad weather code is fed to your 'wx_code_map' method, it crashes. > > Traceback (most recent call last): > File "./ASOS_plot_data_for_archive_hourly_ISU.py", line 437, in <module> > plot_station_data(date,site,sitetitle,df) > File "./ASOS_plot_data_for_archive_hourly_ISU.py", line 375, in > plot_station_data > wxcode_num = wx_code_map[wxcodes.split()[0]] > KeyError: '-FZRAGR' > > Might be nice to have a more graceful exit (like returning 0) when that > happens.
