Hi im having troubles on printing all the values of a column on my csv file which includes duplicate values. The .unique is good to print a column with all unqiue numbers. I was wondering what do i use to print all values in a column with duplicate values without the numbering column involved

[ganderamu]

[menachemgerst]
