-The `pandas.apply()` method allows you to apply any function to rows or columns in a `pandas.DataFrame`. For example, you can use it to perform operations on specific column or row values. When you use `.apply()`, you can specify whether you want to apply the function across columns `(axis=0)` (the default) or across rows `(axis=1)`. 
+The {meth}`.apply() <pandas.DataFrame.apply>` method allows you to apply any function to rows or columns in a {class}`pandas.DataFrame`. For example, you can use it to perform operations on specific column or row values. When you use `.apply()`, you can specify whether you want to apply the function across columns `(axis=0)` (the default) or across rows `(axis=1)`. 
 
 For example, if you want to apply a function to each row of a DataFrame, you would use `df.apply(your_function, axis=1)`. This function is especially useful for applying logic that can’t be easily achieved with built-in pandas functions, allowing for more flexibility in data processing.
