Let’s see how to get all rows in a Pandas DataFrame containing given substring with the help of different examples. (3) Using isna() to select all rows with NaN under an entire DataFrame: df[df.isna().any(axis=1)] (4) Using isnull() to select all rows with NaN under an entire DataFrame: df[df.isnull().any(axis=1)] Next, you’ll see few examples with the steps to apply the above syntax in practice. When the number of rows is greater than max_rows, the Dataframe is truncated and it is shown min_rows rows. In pandas when we print a dataframe, it displays at max_rows number of rows.
