Dynamic segmentation with respect to a control factor

[ChukwuemekaEzeiruaku]

Is there a way either with python scripts or other solution to dynamically segment the following table?

Input table (not a feature class)

Item ID	Begin	End
1000	0	1
1001	0	5
1002	1	7
1003	4	5
1004	3	5

Each segmented section (from-to) should have all the item numbers written to a field that is within a certain range. From the input table, the final table should look like the one below:

Output table

Begin	End	Item ID	Item ID
0	1	1000	1001
1	3	1001	1001; 1002
3	4	1002	1001; 1002; 1004
4	5	1003	1001; 1002; 1003; 1004
5	7	1004	1002

Thanks.

I knew there had to be a numpy solution too; unfortunately, I know squat about it. I also like your dictionary comprehension line with the search cursor better than mine. Thanks for posting, Xander Bakker

Hi Blake, your solution worked but i got an error from line 37 as shown in the image.

Also i got a table with half the records from the input table.
