One way to deal with empty cells is to remove rows that contain empty cells.This is usually OK, since data sets can be very big, and removing a few rows will not have a big impact on the result.ExampleGet your own Python Server Return a new Data Frame with no empty cells: import ...

Next, we’ll fill those values downwards into the ‘empty’ (NaN) cells. To do this, we’ll use Series.fillna() with the ffill (forward fill) option. durant_ft_test['start_game'] = durant_ft_test['start_game'].fillna(method="ffill") durant_ft_test game_descriptionshot_typeresult...

Table 1 shows our example DataFrame. As you can see, it contains six rows and three columns. Multiple cells of our DataFrame contain NaN values (i.e.missing data). In the following examples, I’ll explain how to remove some or all rows with NaN values. ...
Any cells which contain nan values will be highlighted in yellow. Any string column cells which are empty strings or strings consisting only of spaces will be highlighted in orange. ❗will be prepended to any column header which contains missing values. Highlight Outliers Highlight any cells fo...
