Solution 1:[1]

~ Operator performs a not logical operation bitwise, which means it takes a set of data and negates the condition that you are performing on your dataframe.

In your case, df.index.isin(df_to_remove) will return a certain set of values, like [True, False, True...]

With ~ operator, the output would be the logical negation, [False, True, False...] or just the negation of the original condition.
