Charles Kelly explains how to select information from Pandas data frames and series.
- [Teacher] The selection file from your exercise's…file folders is pre-populated with import statements…for pandas and numpy, a numpy data set,…a data time index, and a sample data frame.…The purpose of this video is to provide examples…of selecting information from a data frame.…The pandas' developers provide this warning:…while standard Python/Numpy expressions for selecting…and setting are intuitive and come…in handy for interactive work,…for production code, we recommend the…optimized pandas data access methods.…
Begin by placing your cursor in the import cell…press shift enter, this creates pd as a name space…for pandas and np as a name space for numpy.…Execute this cell as well, this initializes the information…within our sample data frame.…Now we'll look at selecting column information,…or selecting information by column.…That is, we'll select every row within a particular column.…For example, if we use our sample data frame,…and then we index it with C,…the information that we receive is…all of the information from column C above for every row,…
