Charles Kelly explains indexing and selection for Pandas data frames.
- [Instructor] In this video,…we'll examine techniques for indexing…and selecting…from data frames.…We'll examine these operations.…Select a column,…select a row by a label,…select a row by an integer,…select multiple rows…and select rows with a Boolean mask.…This is the syntax for each of these operations,…and this is the result of each of these operations.…If you'd like more information,…you can find it at this U-R-L.…The indexing file in your exercises file folder,…is pre-populated…with import statements for pandas and numpy,…and a data set in the form of a dictionary.…
Begin by placing your cursor in this cell,…execute the import statements…by pressing shift enter.…Do this same thing for the data set…and create the produce data frame.…In our first example of selection,…we'll select information from a data frame…using strings as an index.…As you can see, we've obtained…all the values in the fruits column.…Apple, bananas, pineapples, berries.…We can also use a list of strings…to select multiple columns from a data frame.…
