Sir when we passes calcSales fun in lambda expression what is x[total sale amount] and how it x is referring to df column at 6:47

[@ProgrammingIsFunn]

Hi Aklesh, using the lambda function we are applying the calcSales function on dataframe right, so x is lambda variable by which we are accessing the dataframe columns "Total Sale Amount". for more info watch lambda tutorial it will help you. kzbin.info/www/bejne/nJK5m5-KrcaFarc

3:10 doesn't make sense, so are you getting the max price for that customer or overall? wouldnt max(df.Quantity) give you the max quantity of the entire DataFrame, not just for this customer? .. why was only 1 customer record shown for Willie Oliver, I don't understand that part? wouldnt df.loc[:,"Customer","Total Sales Amount"].apply(max,axis=rows) give all records and the max values for each record ? , a bit confused

[@ProgrammingIsFunn]

Hi tobedeleted, here we are getting the max price for overall customer in DataFrame. So, we will have only single customer against the max quantity and sales.
