Actually, with the sophisticated dtypes (datatypes) now in numpy, you can now store strings and floats in the same array. However, you solution sounds sensible and simpler than creating such an array, so you may prefer to carry on.
Thank you, Andrew. Thinking more about the process, I decided that writing the parsed and processed stream into a sqlite3 table is the better approach. This gives us permanent storage of the digital images of each scanned paper form so they can be compared if a data audit is required. Also, it is easier -- for me, at least -- to write the SQL select statements to calculate column averages grouped by the two string values. It is these average values that are to be inserted into a 2D array. Rich -- Richard B.
