Hello , When i==0 you append an empty list to arr, so arr[i] is arr[0]. No problem. When i==10 you append another empty list to arr, so arr[i] is arr[10]. Index error because there's no arr[10], only arr[0] and arr[1]. Thanks for your prompt reply... How can i pass this problem Sincerely Tanmoy -- http://mail.python.org/mailman/listinfo/python-list

Better still: ... row = [] for j in range(0,1001,1): row.append(i+j) arr.append(row) ... I tried both the ways... the only thing is its not coming like 0 10 20...1000 . Its coming like 0,1,2,1000.Any answer to the problem. Thanks Tanmoy Mukherjee -- http://mail.python.org/mailman/listinfo/python-list
