How can you retrieve values from a data frame using a single line of code?

edit

To retrieve values from a data frame using a single line of code, you can use the indexing operator [ ] with the row and column numbers or names. For example, if you want to retrieve the value in the second row and third column of a data frame called df, you can use:

df.iloc[1, 2]

Or, if your data frame has column names, you can use:

df.loc[1, 'column_name']

This will retrieve the value in the second row and the specified column.
