label_km_to_miles = lambda s: re.sub(r'[0-9.]+\s?km', '%s (%smi)' % (re.compile(r'([0-9.]+)\s?km').match(s).group(0), km_to_miles(re.compile(r'([0-9.]+)\s?km').match(s).group(1))), s)

'lastquake' command throws exception if the latest significant earthquake in the USGS feed doesn't include a distance in the 'place' field.

Latest quake shows: {"mag":6.3,"place":"Southern East Pacific Rise","time":1542323341050

Note lack of "303km from Dzibania"-style distance measurement.

Regex should be amended to handle a lack of km to convert.

Exception is
