looping through grouped records


Recommended Posts

Hello All,

I am new to python scripting and need to write a code to basically loop through selected records of a feature class.

Here's a sample of how attribute table looks like. I have also attached a pgdb.

OBID ID FromLeft ToLeft FromRightToRight Flag

1 1 0 9 2 10

2 1 8 19 12 24

3 22 3 23 2 12

4 3 0 0 4 16

5 1 21 29 26 30

6 3 0 11 18 22

7 1 27 31 32 42

8 3 13 19 22 28

Here's what I am trying to do.

1. Grab all the records with same id (say ID=1)

2. sort "FromLeft" in ascending order

3. Skip the first record

3. compare "FromLeft" value (ie. 2nd record) with "ToLeft" value of previous record (ie. 1st record)

4. if "FromLeft" value <= "ToLeft" value of previous record, export both records to a new table or flag it by populating a new field

5. Sort "FromRight" and repeat the same process

6. Once this is done for all the records with ID=1, move on to next set of records with same id, (say ID=3)

Any help will be greatly appreciated.

Thank you.
