I usually use flattener preview to outline or give them all my fonts to install. keep: It is to control how to consider duplicate values.It can have 3 values. check if the subset without the current number was unique (see duplicates[] = false) and whether adding the current number produces a unique sum, too. If we want to remove duplicates, from a Pandas dataframe, where only one or a subset of columns contains the same data we can use the subset argument. gapminder.drop_duplicates(subset="continent") We would expect that we will have just one row from each continent value and by default drop_duplicates() keeps the first row it sees with a continent value and drops all other rows as duplicates.
