Analyzing Columns [1/4]Analyzing Columns [1/4]

We can see that only two types of data are presented in the dataframe: object and int64. Columns that have an object data type contain string objects, which makes aggregation impossible for them. Among these columns are Weekly_Sales, Temperature, Fuel_Price, and others. It is obvious that all the mentioned columns must be numerical. We might be interested in comparing the revenue for different dates, but with object data, it's impossible.
