Something to keep in mind is that not all strategies make sense for operations that involve only a single variable, like `isnull`, but I guess for those all string options except `drop` mean ""keep the attributes"".","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,587895591
