[GRASS-user] GRASS GIS 7.8.5 v.distance

[Stefan Blumentrath]

Hi Kelsey,

Try: "from_"

So, 
gs.run_command('v.distance', 
    from_ = 'buildings', 
    to = 'mappedStreams',

The problem is indeed that from is a keyword...

Cheers
Stefan

Hi,

I am trying to use the v.distance function in GRASS GIS 7.8.5, however, it won't accept 'from' as a parameter as it's a python keyword (I think). When I use 'FROM' I get an error saying:

WARNING: Illegal filename <FROM=buildings>. Character <=> not allowed.
ERROR: Vector map <FROM=buildings> not found

This is the code I'm trying to run:

gs.run_command('v.distance', 
    FROM = 'buildings', 
    to = 'mappedStreams', 
    upload = 'to_attr', 
    column = 'stream_id', 
    to_column = 'OBJECTID', 
    output = 'distanceLines', 
    overwrite = True)

Any help would be greatly appreciated.

Thanks!
