I'm trying to get better with pattern matching but even after years of using MMA it's still a murky concept. The docs are actually pretty good in this regard but I still struggle. In this situation I have a list of real estate items (that are strings) which I'm trying to clean up. I've tried the below 2 methods and have not been able to delete the "HVAC" elements required from this list.
DeleteCases[featureList, StringContainsQ [#,"HVAC"] & ]and
DeleteCases[featureList, __~~"HVAC"~~__]Both return the same list back:
{ML #,Property Type,SubSpcSqFt,Land Sz SF,Building Type,List Date,Yr Blt,Address,Area,Class,Clear Ceiling Ht (Feet),Lot Frontage (ft),Lot Depth (ft),Zone,Price,Sale Type,Transaction Type,Zoning/Land Use,Amenities-HVAC System,Building Type-Freestanding,HVAC-See Realtor Remarks,HVAC-Baseboard,HVAC-Central A/C,HVAC-Common Water Heater,HVAC-Electric,HVAC-Forced Air,HVAC-Heat Pump,HVAC-Hot Water,HVAC-In-Floor,HVAC-Make-Up Air,HVAC-Mixed,HVAC-None,HVAC-Radiant,HVAC-Rooftop,HVAC-Separate Controls,HVAC-Separate HVAC Units,HVAC-Separate Water Heaters,HVAC-Space Heaters,HVAC-Steam,HVAC-Window A/C}What is the correct way to filter out any string containing "HVAC"?
