Hi Professor Could you please explain below statements: 1. Also based on the header line, report any lines that do not have the same number of cells. (Cells are allowed be empty.) Should we ignore this rows or to print a message? 2. cantril_data_cleaning expects three .tsv files corresponding to the three files from Our World in Data. The input files may be in any order. The output is expected to be a tab-separated data directed, as before, to standard output. The input files may be in any order so that means only the three given files namely: gdp-vs-happiness.tsv,homicide-rate-unodc.tsv,life-satisfaction-vs-life-expectancy.tsv can be passed in any order and if any other files with different files names(atleast 1) passed should exit with an error message(am i correct?) Thanks.
