please help...writing set to a file
Good day every one! I got this python program that returns me a set like this.. Set ([‘A\n’, B\n’, ‘C\n’, ‘D\n’, ‘E\n’, ‘F\n’, ‘G\n’ ]) And a list pp = [‘100\n’ ‘200\n’ ‘300\n’ ‘400\n’] I was reading this from a file…. How can I transform this to something that looks like this Column1 Column 2 100 A 200 B 300 C 400D E F G And then write this to a file??? thank you for taking your time!!! -- http://mail.python.org/mailman/listinfo/python-list
