If I wanted to accomplish looking up values from one table based on a
value from another table or file, how would I go about doing this in
Python? Would I build a dictionary or an array?
exp:
Table1:
Site = 103
Lane = 2
Dir = ? # Get this from Table2
Table2:
Site, Lane, Direction,
103, 1, 1
103, 2, 1
103, 3, 5
103, 4, 5
Normally in Access I would just use a Dlookup and be done with it, or
use a Recordset in VB. Thanks guys.

What about using a database ? Like SQLite ?
Else, the canonical data structure for quick lookups is of course the dict.

Ah, yes, that would appear to be a better means to retrieve data. I
visited the site, which version should I download? Thanks.

If I flipped the Table being looked up not to repeat, would that make
things easier to look up a value in?
Exp:
Table1
Site = 103
Lane = 1
Direction = ?
FHWA Lane = ?
Table2
Site, Lane 1, Direction 1, FHWA Lane 1,
103, 1, 1, 1 ko****@hotmail.com a écrit :
