I need to ask for user input based on a column of data in a csv file that will be uploaded at the beginning of the program. One of the columns is used to differentiate where each row of data comes from. I can separate this column and eliminate duplicates, but I need the user to select which of these values they want before the program can continue.
For example, the choices for the user may be A, B, C and I need the user to select which one they before the program continues to run. However, the column of data that the user selects from does not necessarily ever have the same value or length.
Any help is appreciated!
