Join Charles Kelly for an in-depth discussion in this video Operations, part of pandas for Data Science.
- [Instructor] The operations file…from your exercises file folder…is prepopulated with import statements…for pandas and num pi.…It also contains a num pi data set,…a date time index and two sample data frames.…It initializes a variable named starting date…to July 1, 2016.…Begin by placing your cursor in the import cell…and execute the cell by pressing shift+enter.…Our first example of a built in operation…is panda's describe function.…
You can execute this cell again by pressing shift+enter.…By default the describe function returns…eight popular descriptive statistics.…You can see that I've used the display precision option…to set the display output to two positions…after the decimal point.…In our next operation we'll use the mean function…to calculate the means of each column of data…in our data set.…As you can see each column is listed…in the left hand column and the value…of the mean for each column is listed…in the right hand column.…
In contrast to the column's means,…you can obtain the row means by passing…
