This is a continuation of my pursuit to learn Python. I have been tinkering with this for a number of years and I am back at it again. I am stuck and need some guidance.
This is related to other posts that I have made in the past. For example: Searching for Lottery drawing list of ticket match: https://groups.google.com/forum/#!topic/comp.lang.python/sHLPrfmY3q4 I have a text file with the results of lottery drawing like so: Draw Date WB1 WB2 WB3 WB4 WB5 PB PP 01/02/2016 42 15 06 05 29 10 2 12/30/2015 12 61 54 38 36 22 3 12/26/2015 65 40 44 59 27 20 2 12/23/2015 67 16 63 38 55 25 4 12/19/2015 30 68 59 41 28 10 2 12/16/2015 09 42 10 55 32 06 2 12/12/2015 62 02 30 19 14 22 2 12/09/2015 16 46 10 56 07 01 2 12/05/2015 47 33 68 27 13 13 2 12/02/2015 14 18 19 64 32 09 2 11/28/2015 47 02 66 67 06 02 3 11/25/2015 53 16 69 58 29 21 2 11/21/2015 37 57 47 50 52 21 3 11/18/2015 40 17 46 69 41 06 2 11/14/2015 66 37 22 14 45 05 3 11/11/2015 26 04 32 55 64 18 3 11/07/2015 50 53 07 16 25 15 2 11/04/2015 12 02 17 20 65 17 4 10/31/2015 09 47 20 25 68 07 2 10/28/2015 56 62 54 63 04 10 2 10/24/2015 20 31 56 64 60 02 3 10/21/2015 57 32 30 42 56 11 4 I load the lottery drawings into memory for searching with the following code although, it is incomplete. I am stuck and need some guidance. The set datatype seems to be the best for searching, but how best can I implement it? And I want the results to highlight the numbers that were matched. For example, if the white balls in the drawing are: "42 15 06 05 29" AND the numbers on the lottery ticket are: "06 15 32 42 56" THEN the display might look like: "06* 15* 32 42* 56" WHERE * signifies a match. ############################### from datetime import datetime class Powerball(object): """Summary of class here.
