Create dataframe from the unique data of two dataframes

[Pedroski55]

Yeah, that's all pandas is doing: checking things in lists. Each row or column is a list, Just, you can't see behind the scenes, so you don't see that, then it seems like arcane magic.

I would point out that you do not have a column "Amount", you posted "Amt", so you will get an error there, like I did first time around.

Columns:
"Date", "Acct", "Type", "Amt", "Category", "Note", "Extra"

Still like this one-liner:

res = df1[~df1.isin(df2)].dropna()
