actvity 2 instruction indicates to drop the unwanted columns after reviewing in excel. unclear
i would expect questions along the lines of - should i drop in excel, should i reopen in python and drop there? how do i know i dont want some columns ? acc to what criteria ? is this for the next step of the activity ?

@sandrabosk

on activity 2 in this lesson it isnt clear how the lambda and excel element are related to eachother ? sorry!

and we had some null management with categorical data from the lesson which isnt applied in the activity

@sandrabosk

current instructions indicate that columns should be dropped, but the solution shows that the data frame is cleaned of null values in those columns. this is in line with the learning points of the lesson at this time where we are learning about null management
