search for "does-not-contain" on a dataframe in pandas

I've done some searching and can't figure out how to filter a dataframe by df["col"].str.contains(word), however I'm wondering if there is a way to do the reverse: filter a dataframe by that set's compliment. eg: to the effect of !(df["col"].str.contains(word)).

Can this be done through a DataFrame method?

You can use the invert (~) operator (which acts like a not for boolean data):

    new_df = df[~df["col"].str.contains(word)]

, where new_df is the copy returned by RHS.

contains also accepts a regular expression...
