Чтобы фильтровать столбцы DataFrame по списку столбцов, вы можете использовать различные методы на разных языках программирования. Вот несколько часто используемых методов:

1. Python (Pandas):

   # Assuming 'df' is your DataFrame and 'columns_list' is the list of columns you want to keep
   df_filtered = df[columns_list]

2. R (dplyr):

   # Assuming 'df' is your DataFrame and 'columns_list' is the list of columns you want to keep
   df_filtered <- df %>%
    select(all_of(columns_list))

3. SQL:

   -- Assuming 'table_name' is the name of your table and 'columns_list' is the list of columns you want to keep
   SELECT column1, column2, ... -- Specify the columns you want to keep
   FROM table_name;

4. Юлия (DataFrames):

   # Assuming 'df' is your DataFrame and 'columns_list' is the list of columns you want to keep
   df_filtered = df[:, columns_list]
