Python pandas.apply() is a member function in Dataframe class to apply a function along the axis of the Dataframe. For example, along each row or column.  Pandas DataFrame is the two-dimensional data structure; for example, the data is aligned in the tabular fashion in rows and columns. In this tutorial, we will see how to apply formula to entire column and row in Pandas with example.

How To Apply Formula To Entire Column and Row

Pandas.dataframe.apply() function is used to apply the function along the axis of a DataFrame. Objects passed to that function are Series objects whose index is either a DataFrame’s index (axis=0) or a DataFrame’s columns (axis=1).

By default (result_type=None), a final return type is inferred from a return type of the applied function. Otherwise, it depends on the result_type argument.
