I am trying to create a python expression to insert into the expression
calculator that fills a column for me in the attribute table, but am
struggling to find the correct syntax - or even successfully implement the
simplest of python expressions. The table shows the compatibility of
Land-use A with each instance of land use B, but I need to create a final
column that can select the correct number from the correct column, depending
on what is in the Land-use B column. An example of my attribute table is
shown below.
**Compatibility:**
ID | Land-use A | Agr | Urb | For | Com | Pub | Land-use B |
Compat
1 N 1 4 3 0 2
Agr
2 G 2 3 5 1 0
Pub
3 K 4 2 3 5 1
Urb
4 N 1 4 3 0 2
Urb
An example of my desired attribute table can be seen below:
**Desired:**
ID | Land-use A | Agr | Urb | For | Com | Pub | Land-use B |
Compat
1 N 1 4 3 0 2
Agr 1
2 G 2 3 5 1 0
Pub 0
3 K 4 2 3 5 1
Urb 2
4 N 1 4 3 0 2
Urb 4
Perhaps it is possible to do this in the gvSIG expression calculator without
import a .py file - but either way I can not seem to get the syntax right.
Any help would be much appreciated.
