That doesn't make much sense, as a sepcification. CSV is by design a data format in which every data row has the same structure: the fields always have the same meaning, in the same order. > I am trying to see if I can read in a csv file and search for a > certain date range like 1/2/2016 to 1/5/2016. You can, by breaking the problem into simpler problems: * Get the rows into some collection of structured records. (The Python standard library's ‘csv.DictReader’ is your friend here.) * Identify which field of the record is the data on which you want to filter. (For a collection of records you retrieved from reading a ‘csv.DictReader’, you need to know which field name has the dates you're interested in.) * Construct an expression that takes an arbitrary date value as found in that field, and interrogates it by some comparison that evaluates to True when the value is in your specified range and False otherwise. * Construct a new collection of records, by iterating the full collection and only accumulating the ones which match your criteria. Each of those is much simpler that the original problem. Solve each of them separately, and it should then be much easier to put the solutions together to solve the larger problem. -- \ “Friendship is born at that moment when one person says to | `\ another, ‘What!
