> When using the apply function to apply a function to a DataFrame column, it ends up mixing the column's rows ordering.
> A command like this:
> {code:java}
> def example_func(df_col):
>   return df_col ** 2
> df['row_to_apply_function'] = df.apply(lambda row: example_func(row['row_to_apply_function']), axis=1){code}
