07 Loops
Exercise: Group LoopThe first task is to build a group loop that compares the life expectancy in each country to the average value on the continent where it'slocated.1.1) Read the JoinedCountryTable.table file by executing the top Table Reader node. This table contains information about thedemographics, geolocation, and travel risks in the different countries/territories in 2020.1.2) Start a group loop that handles each continent in a separate iteration1.3) Build the loop body. - Calculate the average overall life expectancy on the continent- Transform the value into a flow variable- Use the Rule Engine node to assign each country the value "below" if their overall life expectancy is below the average and the value"above" otherwise. Append a new column.1.4) Close the loop by concatenating the rows from the different iterations. Is the life expectancy in France below or above the Europeanaverage?
